1.Structure introduction :
The boiler is a horizontal internal combustion three-circuit wet-back fire tube fast-loading boiler. The boiler body is assembled and shipped from the factory, and the tail is equipped with economizer and condenser to reduce the exhaust gas temperature.
The boiler body is mainly composed of a drum, a corrugated furnace, a reburning chamber, two sets of smoke pipes, an inspection hole ring, a front and rear smoke box, and an explosion-proof door. The furnace, the reburning chamber, the smoke pipe, and the inspection hole ring are all installed in the boiler shell and completely immersed in the furnace water.
The flue gas flow process is furnace hearth → reburning chamber → first set of flue pipes → front flue box → second set of flue pipes → rear flue box → economizer → condenser → chimney, and the flue gas flows in an S-shaped flow. The insulation layer of the boiler is aluminum silicate refractory fiber, which ensures that the surface temperature of the boiler shell is lower than the national standard, and the heat loss is very small.
2. Uniqueness of WNS boiler
a. continuous innovation
Innovation is the company 's survival, Nantong WNS boiler in 2000 with six innovation points in the domestic patent application, patent number : 00241010.9.、
b. energy saving gas
Ⅰ. Gas boiler expensive fuel costs so that owners have to seriously consider how to reduce this expenditure, and the minimum fuel consumption is the subject of our company for many years of tireless research, the company 's design and equipment everywhere the performance of this deliberate pursuit.
Ⅱ.The boiler heating surface is rich, the use of efficient heat transfer element threaded pipe, boiler thermal efficiency is high.
Ⅲ. Configure the energy-saving device and the condenser, within the normal load range neither produce too much condensate, nor make the exhaust temperature is too high.
Ⅳ. For any type of boiler, the fan pressure of the burner has a considerable amount of abundance, which is enough to overcome the additional resistance caused by the possible installation of energy-saving devices and condensers to ensure that the output of the boiler does not decrease at all.
Ⅴ.According to the change of the steam pressure at the outlet of the steam boiler, the output of the combustion machine is automatically adjusted and the combustion machine is automatically started and stopped to stabilize the steam pressure in the most suitable range without unnecessary repeated heating and excessive heating.
Ⅵ.Use the famous European and American brands of burner, and ensure the best match between the boiler and the burner, and automatically adjust the output of the burner according to the boiler load.
Ⅶ.The proportionally regulated burner can not only operate stably at a desired load, but also save more fuel than the constant size of the fire.
Ⅷ.The surface temperature of the boiler insulation shell is below 35 °C, and the heat loss is very small.
Ⅸ.High-quality imported valves to avoid leakage caused by the shutdown accident and hot water loss.
c.safe and reliable
Ⅰ.The overall annealing of the boiler to eliminate welding residual stress, not only improves the safety and reliability, but also greatly extends the service life of the boiler.
Ⅱ.Gas boiler furnace hearth is longer than the general manufacturers, furnace heating surface is larger, in order to avoid the gas caused by furnace outlet flue gas temperature rise too much.
Ⅲ.Three-pass full-back structure, the reburning type and the flue pipe in the drum are all immersed in the boiler water. The flue pipe is fully welded with the front tube plate of the reburning chamber, rather than the ordinary angle welding connection. The inner side of the flue pipe inlet is ground into a circular arc to slow down the stress concentration and make the heat transfer easier, effectively preventing the thermal fatigue crack in the tube hole area of the tube plate.
Ⅳ.Ignition program control, flameout detection and alarm, valve gas leakage detection and alarm, wind pressure and gas pressure detection and alarm to ensure combustion safety.
Ⅴ.Double boiler temperature display control instruments and safety devices, all use international brand-name products to ensure the safe and economic operation of the boiler.
Ⅵ.Explosion-proof door, check the door cover and seat are conical shape side seal ( rather than plane seal form ), smoke box door cover convex seal, ensure the good sealing of the boiler.
Ⅶ.Before leaving the factory, each boiler has passed the sealing test of 300mm H2O pressure.
d. Intelligent
Perfect start-up and shutdown procedures, automatic detection of operating conditions and faults, identification and prompts, reliable self-locking and interlocking functions, automatic adjustment of boiler and burner load functions, and imported internationally renowned brand control components not only make the operation of the boiler very simple, but also ensure that the boiler is always in a safe and economical condition.
e.easy to operate，appearance is neat and tidy
Ⅰ.The touch screen on the control system makes you clear about the boiler situation, and the operating parameters can be set at any time.
Ⅱ.Although the manhole device on the top and side of the drum increases a lot of manufacturing costs, it provides great convenience for inspection and maintenance.
Ⅲ.The outer packaging of stainless steel makes the boiler beautiful and durable.

- Q:all my radiators have tvrs and i have no thermostatic control.obviously i have various controls on the boiler, but does anyone know what the best settings would be to get the optimum benefit and the cheapest use..etc the boiler is 3 years old and i have lost the instructions..thanxas with the price of gas i have been wary about putting the heating on.thanks
- To run your boiler efficiently you will need a interlock which is basically a room stat which will electrically turn the boiler off when the desired set temperate has been reached. At the moment your boiler will cycle on even when your radiator valves are satisfied via a bypass which is a safety feature to allow the hot water in your system to circulate so that the boiler doesn’t overheat in the event that all your radiators reach temperature and the TRV valves close. Get a room stat fitted, Wireless one are available if the routing of a cable is difficult.
- Q:I am in the process of purchasing a home. I fell in love with an old farm house in my area and am thinking about placing a bid for it. It has a Boiler system for heating the house. My questions for anyone who has experience with them in their homes are;1. Is it very hard to maintain?2. Is it alot more expensive to run it in the winter?3. What are the cons of having one?I asked my realtor, but he isn't too familiar with them, and I can't seem to find out any real pros or cons on the internet searches.Thanks in advance.
- 1. They're easy to maintain: just be sure it has enough water. 2. More expensive than what? Spending $10,000 or $15,000 to replace it with something else will take a very long time to break even. 3. The radiators can't be moved around like furniture. :-) Resist the urge to drain and refill the water in the system. It will look dark and gunky and seem to scream Change me! If you do, there will be a year or two of hissing, gurgles, and growls until the mineral balance between the pipes and the water reaches equilibrium again—at which time it will be murky and gunky. Except the pipes will have lost more material.
- Q:My boiler is building up pressure from 29 to 30 psi. I have drained water out of the air tank to bring the pressure back to 12 psi. The pressure continues to go back to a high number. Is my air tank shot and how do I fix my problem?
- check to make sure your breather on the top of your expansion tank is open a 1/4 turn. if it is, may be the tank
- Q:So I just installed a Titan tankless water heater. I’m not a hippy tree-hugger, mind you. I just HATE sending money to National Fuel. In any event, it got me thinking that if the water used in my boiler system was heated through this mechanism, my fuel use would decrease to virtually zero. While my electricity costs would increase, the increase should be less than the $300.00 monthly gas bill (and that’s the balanced billing rate… yeah, I’m getting screwed, and that’s AFTER insalling 30 brand new double-pane argon filled windows).Do “flash heating” boilers exist (whereby the water is heated instantly as it passes through a tankless water heater)? If so, do they offer savings over traditional natural gas boilers, enough to warrant the investment? Because I’m not really buying into the whole “your best energy value” thing... what a crock is sh1t that is.I would love to hear what you have to say.Thank you.
- Firstly you are not talking apples and apples here. The Titan is for heating potable domestic and your boiler is for non potable heating water. However there is a way you can save money, the initial output would be expensive. What you can do is install a domestic tank with a heat exchanger, most boiler manufacturers supply, and would need to be professionally installed, so that when you are using the boiler for heat you can be heating your domestic water as well, and when not in use you can switch the Titan heater back on. They do not make any boilers that operate instantaneously like the titan water heater, but you can purchase one with a better efficiency rating.
- Q:Do superheaters and boilers have the same conditions?
- The conditions are similiar on the combustion side of the boiler/superheater tubes as the 2000-3000 degree flue gas/fly ash runs through the boiler/SH passes, with the exception that in the boiler section the heat is transfered through the tube walls via radiation, whereas it is done via convection at the superheater. Inside the tubes, the steam generated at the boiler (the one I work with anyway) runs up to about 800 degrees F at 3500 psi while the steam at the SH is held to 1000 degrees F at 3500 psi. So, the difference isn't all too great so far as pressure and temperatures go. The major difference, as the name implies, is that the steam in the superheater is superheated, which is done to prevent steam from condensing back into water as it makes it's way through the turbine.
- Q:So the hot water from the boiler goes thru a taco pump to the tank on the output or return side it goes thru a small valve with a knob. Does anyone know what this valve is for and how should it be setup? From this valve it goes into the boiler return.
- The boiler should actually be sending steam to the hot water tank, where it passes through a heat exchanger that heats the water in the tank. The valve adjusts how much steam gets through (and thus how hot the water in the tank stays). Ideally, this would be a thermostat-driven valve, so that the water in your tank is kept at a constant temperature.
- Q:What are the benefits of one?
- Unless you're a pastry chef or a chocolate maker, I'd say no. These days, most people put a metal mixing bowl over a pot of simmering water to get the same results as a double boiler. That is fine for Hollandaise sauce, chocolate dishes, etc.
- Q:What kind of equipment does the thermal power system include?
- The purpose is to improve the initial pressure in the case, so that the steam turbine tail steam humidity is not too large to ensure long-term safe working steam turbine.
- Q:Gas boiler thermal efficiency problem
- The total calorific value of the gas is: 37.7MJ / cubic × 10800 cubic = 407160 (MJ)
- Q:The house is 4000 sq feet. The new boiler would be a Weil-McLain EG series. The boiler is in a stand-up basement area that is accessible from the outside. The contractor is quite reputable, but known to be expensive.Thanks in advance for your help.
- Get some other prices. It sounds a little high but all installs are different. Be wary - steam can be very tricky - especially the near boiler piping. There are not many people out there nowadays that understand steam systems unless they've been around awhile. Ask anybody bidding if they regularly service and replace steam boilers. This guy may be high because he knows he will have to make piping modifications that other contractors don't see. And no on in their right mind would replace a steam boiler for $500 labor unless they are clueless. Besides the boiler, the materials alone could run $300-$500 depending on the installation. A simple water level elevation change due to the difference between the old and the new boiler can throw off things.
