1.Structure introduction :
This product is a double drum ( S ) vertical ( Z ) room combustion ( S ) fuel ( Y ) [ or gas ( Q ) ] boiler.
a.The boiler is a natural circulation double longitudinal drum ' D ' boiler. The left side is the furnace, and the right side is the convection tube bundle. The boiler adopts micro positive pressure combustion. The burner is arranged on the front wall, and the convection tube bundle is arranged on the right side of the furnace. The flue gas generated after the fuel is fully burned in the furnace is transversely scoured from the rear outlet of the furnace to make the convection tube bundle fully endothermic. Then it enters the economizer from the rear of the boiler to make the economizer further endothermic and finally discharged into the chimney.
b.The upper and lower double drums are connected by welding, and the upper drum is supported on the lower drum by convection tube bundle. The lower drum is supported on the base by two supports respectively. The front support is movable and the rear support is fixed. The weight of the whole boiler body is concentrated on the support and then transmitted to the ground. In order to obtain good conditions in the pot, there are internal devices such as water supply pipe, overflow tank, underwater orifice plate and uniform orifice plate, as well as continuous sewage discharge.
c.The cross section of the furnace is ' D 'shaped, and the water wall of the furnace is composed of a dense row of tubes and a finned tube at the rear of the furnace to form a radiant heating surface. There are fire holes in the middle of the rear wall, and test holes are arranged below it, generally for the test temperature. There is a well-structured explosion-proof device at the upper left rear to ensure the safe operation of the boiler. The front wall is not arranged on the heating surface.
d. Between the upper and lower drums, dense tubes are arranged to form the convective heating surface. The high temperature flue gas scours the convection tube bundle horizontally forward, so that the convection tube bundle absorbs heat fully.
e. In order to reduce the exhaust gas temperature and improve the efficiency of the boiler, the casting economizer is arranged in the tail.
f.because the boiler is positive pressure combustion, so the use of fully sealed furnace wall. The inner layer of the furnace wall is made of aluminum silicate fiber brick and lightweight refractory brick, followed by aluminum silicate fiber felt, and the outermost layer is all sealed and welded with steel plate as the outer panel.
g.the use of imported automatic burner, can also be selected according to user requirements of domestic burner.

- Q:The role of the boiler
- 3, according to the use of points: life boilers, industrial boilers, power boilers, marine boilers
- Q:I'm in my GCSE year at school and have found a vocation in renewable technologies and the environment. I'm currently doing some work experience for an environmental consultancy firm and just want to start learning as much as I can about energy efficiency etc. Anyway, I'm still pretty new to all this and wondered if you can tell me how gas is used in the average home? Does a house itself have its own significant carbon emissions, or do most of these just come from the power stations supplying the mains?
- Natural gas or propane gas burners if not adjusted properly can produce CO gas. This gas is picked up better than oxygen in a person, and it kills about 170 people every year in the US. Therefore, laws prohibit directly heating a house with combustion gas. An approved heat exchanger is required to separate the air in the home from combustion gasses. The combustion gas is vented outside. The efficiency of the heat exchanger varies widely, so it is wise to consider this efficiency when buying a new heater if you value the environment and would like to save money on gas. In the eastern US, oil or coal is burned in a boiler to heat water, which is circulated to radiators in the house. Again, poor maintenance will produce more CO, plus other gasses like NOx and SO2. SO2 because cheaper grades of coal and oil have sulfur compounds in the fuel. An efficient boiler will save on fuel costs and result in less damaging pollutants released for a given amount of heat produced.
- Q:What does the boiler mean?
- Boiler is an energy conversion device, the input energy to the boiler fuel in the chemical energy, power, boiler output with a certain heat of steam, high temperature water or organic heat carrier.
- Q:Have a new weil 155 ultra gas hot water boiler (no external hot water) For experiment, the temp outside was 45 deg and home temp was 62 deg. The water temp in boiler was reading 66 deg. I turned thermostat up to 71 and about an hour and a half to two hours later the house was heated including basement and two upper floors to correct temp. I estimated the gas used at 3-3 1/2 cubic feet or about 4 dollars. What I am unsure about is after the home is heated the water temp in the boiler will continue to fall and fall from say 155 to 90 or less and then the boiler will fire for a while and maintain temp. Over a period of say 6 hours this may consume 2-3 more cf of gas. According to the guy who installed it, he thinks the system has 25 gallons or so of water, but I dont think he really knew. I;m hoping one of the great yahoo experts can tell me this scenario sounds correct/ Thanks
- I have read your question a few times and I am unsure of what you are asking. Please clarify. Thanks, Newt
- Q:radiator boiler must be clogged/ is dripping a lot. How do I unclogg?How do I know if it is expan ves or PRV?
- depends on what kind of boiler you have. Is it a combi boiler, do you have a hot water cylinder in the house?. Does it drip when the system is cold or when it is heating up. If it drips all the time even when cold and the filling loop is still connected it is most likely the PRV. Disconnect the flexible connection between the incoming cold main and the heating circuit under the boiler (filling loop). This connection sould be disconnected all the time, note the pressure on the gauge it should be about1.5bar when cold, if it is higher than this you will need to reduce the pressure by operating the presure release valve (I presume that is where it is driping just now). Turn on the boiler and watch the gauge, if it rises up to about 3bar and starts to drip. Then it is the expansion vessel, it may need toped up or less likely replaced.
- Q:We just had our boiler looked at and it was determined that we needed a new aquastat. We had that replaced and it worked for about a week. Well now the boiler once again shuts off before the house gets any heat. any idea what could be the issue?
- USA Unfortunately, that is like asking Why doesn't my car start? There are a hundred reasons. The aquastat maintains the temperature of the water only in the boiler, not the temp of the house. It acts the same as a thermostat in a water heater - it keeps the water hot in the water heater. If the boiler is heating up, but the house is not getting warm, for some reason the circulation system is not working. Have the system checked to make sure the circulator pumps, or zone valves, or both, are working properly from the thermostats.
- Q:hi all..just turned on my heating and had water running from the back of my OCEAN ALPHA 280 COMBI BOILER. whats happened? cant get to the problem because the leak is behind a metal back plate on the boiler.. read some things about the HEAT EXCHANGER?any suggestions?
- good chance it is the aav leaking
- Q:I have a Laars Mini-Therm 2 Boiler system that heats my house. We can't get the house temperature in the house above 55 degrees. Can anybody help me?
- There are several reasons that it might not be working.Let's start at the beginning. When the thermostat calls for heat, the vent damper opens. Is it open? The next thing to happen would be burner ignition. Do you have a standing pilot or spark ignition. Can you see the pilot? Is the boiler itself cold or warm? If you have a pilot that is burning, If the damper is fully open, and you have a pilot, I would check the gas valve next. Before ALL of this, try the obvious. Can't tell you haow many calls I have been on where the burner switch was mistakenly shut off, or the batteries in the thermostat were dead.
