Product Description:

Energy efficiency and Environmental protection, Better Quality and Cheaper Price. We would like to provide every kinds of  'Gas Boiler','Circulating Fluidized Bed Boiler','Boimass Fuel Boiler' and looking forward to your kind enquiry.

The Gas boiler has double drums, verticalarrangement and “D” type furnace design with 1 or 2 burners located in thefront wall. there is an air-tight furnace structure with densely arranged tubesand air-proof casing inside. and it is covered with insulation materials andconvex color plates outside. The flue gas takes a U turn. It goes into the 1stconvection tube bank from the furnace, turns after passing the flue, and flowsinto the economizer with finned tubes when leaving the 2nd convection tubebank. The water which goes into the upper drum from the economizer is turnedinto steam by means of natural circulation after passing the convection tubebank and water cooled wall, and then supplied to the user via the main steamvalve.  Upper and lower drums and convectiontube banks are assembled and subjected to a hydrostatic test prior to delivery.The steam boiler has a capacity of 2~75t/h and working pressure of 0.7~5.4Mpa, while the hot water boilerhas a capacity of 0.7~21MW. The feed water and return water temperatures are 95℃/70℃and 115℃/70℃respectively.

The boiler has the characteristics of smallvolume, compact structure, high combustion efficiency, convenient installation, high degree of automation, etc. Adopting micro positive pressure combustionto improve the thermal efficiency and reduce the operation cost. Upper drumadopts Φ 1000 - Φ 1200 diameter to increase the separation height and guaranteethe quality of steam Boiler flue gas partition wall adopt seal membranestructure not only improve sealing and prevent short circuit  but also increase flue gas and improve theutilization ratio of steel and effectively reduce the size of our boiler. holesare pre-opened on membrane wall baffles for timely inspection and repair. Theinspection of convection tube banks is no longer a problem. Convection tubebanks are assembled with special tooling/fixtures, and must pass a hydrostatictest prior to delivery. It not only reduces the installation workload, but alsoensures the boiler quality.

The structure design of densely arrangedtubes and membrane wall with finned tubes ensures that it would never gooverheating outside the furnace tube wall, and the sealing would be maintained.The temperature of insulation and sealing steel plates would not go over 250℃,which ensures the sealing steel plates’ ability of oxidation corrosionresistance.

The design of internal seal casing andexternal embossed casing not only ensures good sealing, but also gives theboiler a better appearance

I have never done this but as far as I think, running a stainless steel liner up the chimney will be a better option.
Q:home repair fixing a boiler problem?
You should have an expansion tank with an air bleeder on it. This bleeder is not working.
Q:How Basic Boiler Works?
There are three basic types of boiler. 1, A simple tank made from plate steel containing a supply of water, a source of heat and distribution pipes, it is fitted with a safety valve designed to relieve excess pressure. This type is limited to pressures of less than 30 PSI. 2, A water tube type of boiler, it is more efficient than the tank type. Water is circulated through pipes that are heated by an open flame that plays over the entire length of the tubes. It also has safety valves. This type is usually used in large apartment buildings and ships. It operates at pressures of 100 PSI. 3, A fire tube boiler, this type has flame running through the pipes to boil water that is in the main body of the boiler, this is a very sturdy boiler and can produce super heated steam, it is used in ships and the pressure is 100 PSI.
Q:what is the purpose of providing fusible plug in boiler?
Safety. Simple explanation. The fusible plug is just a hollow bolt filled with lead which melts if the water cannot absorb the heat generated in the firebox The boiler construction is an inner box for the fire. Surrounded by another box filled with water. The plug is screwed into the top of the firebox. When the fire is lit the heat boils the water. There is no problem if the water keeps the firebox covered. If the water evaporates and uncovers the top of the firebox then the lead melts and steam escapes through the now hollow bolt and puts out the fire. There has been instances where the water has uncovered the firebox top and heat in the fire box has weakened the firebox steel and boiler pressure has distorted the firebox until it has cracked and the violence of the steam escaping has caused the boiler to be torn apart
Q:What is the AQC boiler?
So do not set the cleaning device. At the same time heat transfer tube with spiral finned tube, greatly increasing the heat transfer area, making
Q:whats a bunny boiler?
That is pretty funny. A bunny boiler is a woman who is dangerously obsessive with a man. See the movie Fatal Attraction for that bunny scene.
Q:What liquid is it that circulates through a gas central heating system to the radiators from the boiler?
Yes - it is water. Sometimes if you are in a very cold climate and have a newer system, they will put an additive (like antifreeze) in it to prevent the pipes from freezing if the boiler is in the garage or a colder area. Since water expands and contracts as it changes temp, it is not a closed circuit - If you follow the pipes at the boiler you should see a water supply line which will allow new water to be added when needed. Newer models will also have an expansion tank and an automatic air release in case air gets in the lines. Older models you can usually release the air by turning a screw in the radiator. if when the heat is on, a part of the radiator doesn't heat up it probably has air in it.
Q:What kind of thermostat will control home temperature with outside wood boiler?
Those outdoor boilers aren't as controllable as a gas furnace. I think your best bet is to hook up with the boiler manufacturers for their recommendations. Barring that, look at thermostats designed to work with hydronic systems and see if they can be adapted to work with your equipment. Good luck with it. I'd ask my uncle in Minnesota, but I don't know if he still uses his boiler anymore.
Q:Why won't our combi boiler go on for hot water without turning the radiators on?
As per your other question you have not mentioned the make or model of boiler and different boilers operate in different ways. Normally the boiler on water only will only fire up when you turn on a tap(see your other question for preheat) and if it is not doing so then there is a problem with the boiler. It is impossible to give a definitive reason what without the required make model of boiler due to the differing operating systems between different makes and models.
Q:can we burn black coal/anthracite in a lignite fired boiler?
There are several drawbacks. One is the coal mills are set up for a particular type of coal, they may have to re-worked to process a much harder coal like anthracite. Also, if the boiler is designed for a lower heating value coal like lignite, the heat exchange surfaces may not be optimized for a high heat value coal like anthracite. There may be too much heat release in the water tube section and not enough heat going to the steam section. The amount of ash also affects the heat absorption in the same manner, since the anthracite will probably have less ash than lignite. This will affect the efficiency of the boiler.
