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.
2.Product characteristics

- Q:Im looking to change a heating system from forced air to hot water/baseboard. Im a plumber. I work for a comp., I install boilers but I never had to size a boiler. Im putting in about 140-150' of baseboard in a small 2 story house. I'd love to put in a Williamson 125000btu (or so). Is that too big? The houses old furnace was 110000btu.
- If it has foam lagging on it make certain you scrape it off, as maximum scrap retailers will halve the fee in case you dont. additionally if it has any limescale in it the broking will deduct extra .
- Q:How does the boiler power and tonnage change?
- 1T / h = 1000kg / h = 0.7MW = 720kW = 600,000 kcal / h = 600Mcal / h.
- Q:I've installed a low mass direct vent oil burning boiler (140Kbtu) by LAARS a year ago and twice this year it sooted up so much that it choked itself to the point of burning terribly rich. (thick black smoke out the flue) I'm wondering if it could be my oil, I never had this issue until the last delivery. (This is my second season with this boiler...) I also wonder if using too small of a nozzle can cause this. I'm currently using a .65gph nozzle due to my heating load being relatively small. (Only half of my house is currently on the boiler, I wanted to prevent short cycling the burner.) I opened the fire box and totally cleaned everything from the opening of the flue, clear through all of the internal baffles in the boiler to the intake air line. It was incredibly clogged with soot. Now about a month later, it appears to be in the beginning stages of sooting up again. This morning the boiler locked out, but restarted with ease... but I noticed the black smoke out of the flue again.
- You really should have a boiler technician come in and do, at minimum, a combustion test. This test will tell you how to set the boiler for proper and efficient combustion. This setting is done with both the flue adjustment, incoming combustion air adjustment, and proper burner nozzle size. You have to have the proper test equipment and know how to read the analysis. Make sure when you call a technician, he explains exactly what he is going to do during the service call. If he isn't testing, call another. This will get your burner operating at optimum efficiency. Good luck!
- Q:I have a worcester bosche thermotechnik 240 CCOMBI Boiler RSF.The downstairs radiator bleed screw needs replacing. How do i do this? Here are my presumptions.Turn Water Off, Drain system, replace screw. Then Im stuck.Theres a pipe that joins the Central Heating Return (second pipe from underneath/left) to the Mains Cold Water In.How do i set the taps for this pipe? After turning water back on? Any help appreciated thanks.
- No if the radiator bleed screw need replacing you do not have to drain the whole system shut both taps on the radiator one at either end remove screw this will let some water out so be ready for this when it stops remove the bleed screw replace open both taps bleed radiator Then go to boiler the small pressure gage should be some where between 1.5 and 2 bar if not open the tap on the loop from the mains pipe until the gauge reaches this mark shut off tap job done hope this helps

- Q:What is the concept of "hydrophobic" and "condensate" in the boiler?
- Because the boiler in the early stage of the furnace needs to be fully preheated, and the condensate in the pipeline will cause the pipe due to uneven heat caused by water hammer, thus damaging the pipeline interface flange gasket and the threat of steam turbine equipment safety, if the condensate into the turbine
- Q:Does anyone know of any reputable companies in London that do commercial boiler repairs? I am looking for commenters that have had good experiences. Thanks so much. Any help would be appreciated.
- It is quite often a nationwide service. The guys at Manchester Plumbing Heating know their stuff about industrial boiler servicing and it is easy to recommend them
- Q:can i use spray paint near my gas boiler if i turn it off first?
- DO NOT USE ANY THING NEAR YOUR GAS BOILER THAT HAS ANY KIND OF FUMES. My husband was inflating a wheelbarrow tire in the basement, and was close to our gas furnace, which has a pilot light. The furnace was not running, but when the fumes from the can of tire inflator reached the pilot light, it ignited and he was encircled in flames for a second till the fumes were burned off. Luckily, he was not burned, but the wheelbarrow tire continued to burn and he had to carry it outside while it was burning. If you use a can of spray paint and that happens it may explode in your hand, or you could be burned by the fumes igniting like what happened to my husband. Another thing that could happen is a build up of fumes if the boiler is in an enclosed area and that could ignite and cause an explosion. (Sorry for the capital letters, but I wanted you to notice what I said). (Please be careful, fumes are very dangerous).
- Q:I NEED HELP TO UNDERSTAND WHAT IS A BIOLER INSURANCE
- The Boiler and Machinery policy started out as a way to provide coverage for a common exclusion under any commercial property policy, namely, damage to or caused by: ...any pressure vessel having normal internal working pressure greater than 103 kilopascals (15 pounds per square inch) above atmospheric pressure; or ...any boiler, including its connected piping and equipment, which contains steam or water under steam pressure (except tanks having an internal diameter of 610 millimetres (24 inches) or less used for the storage of hot water for domestic use); (welcome to the wonderful world of insurance legalese). At the beginning of the twentieth century boilers were in common use everywhere from manufacturing to heating, and breakdown or rupture was a real threat. An exploding pressure vessel could level a building! Therefore this policy was created first by specialty insurers who would issue these policies as stand alone policies, however many standard insurers now offer this coverage as an add-on to their commercial policies. Therefore the specialty insurers had to innovate their product in order to remain attractive. Not only does the modern Boiler and Machinery policy cover damage caused to and by pressure vessels, they also cover: damage or breakdown of electrical equipment caused by surges, short circuits or arcing; breakdown of air conditioning or refrigeration equipment including losses resulting from spoilage or loss of use due to the breakdown of said equipment; damage to computer or communication equipment caused by surges or fluctuations including the loss of business income caused by the loss of said equipment; mechanical breakdown of most types of machinery such as water pumps, ventilation fans, escalators and elevators, motors, engines, etc including the loss to business income because of the breakdown of said equipment. Note that production machinery usually has limited coverage or a higher deductible.
- Q:I live in Ireland. We have just bought a new house. In our old house our gas boiler (which was Vokera I think) heated both the radiators the water. However, in this house, the boiler does not appear to be heating the water. It will only heat when we switch on the emmersion. Are we missing a switch that can be turned to allow our gas boiler to heat both the water the radiators?
- boiler systems are set up in zones. If the installer and/or previous owner did not set up a zone for heating domestic water, that would be the problem. If that is the case, you will have to have your plumber install a tank made for this purpose and have him make the tank one of your heating zones.
