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
a. The boiler is micro-positive pressure combustion, the water wall of the furnace with close-packed tubes, good sealing performance, small air leakage coefficient, enhanced combustion and heat transfer, high thermal efficiency, compact size, simple adjustment operating system. The sealing guard plate has a beautiful appearance and the boiler room environment is clean.
b. boiler installation is simple. The boiler is assembled in the manufacturing plant with high assembly degree and strict quality control. After being transported to the site, the economizer, platform escalator, boiler pipeline and auxiliary machine can be put into use.
c.The boiler matching burner has reliable ignition program control, flameout protection and interlock protection device. The boiler has a high degree of automation and can ensure the safe operation of the boiler.
d. It is convenient to start and stop the boiler. The boiler combustion system, steam-water system and flue gas system are simple and reliable. The operation is flexible. The heat capacity of the furnace wall is small.
e. The soot and harmful gases emitted by the boiler are lower than the emission standards of China 's boiler soot, reaching or higher than the national environmental standards, suitable for use in any regional environment.
