The coal-fired steam boiler is a double-barrel longitudinal water tube chain grate or reciprocating grate boiler, with small heating area, sufficient output and strong load regulation ability. Quick loading steam boiler furnace volume is large, with better dust settling function. The boiler convection tube bundle adopts “S” type structure, which has good infection effect, high thermal efficiency, good dust removal effect and convenient dust removal. Can burn the coal with higher ash content, fire fully, burn thoroughly. Boiler drum volume is large, the internal device is complete, steam quality is good, is medium and small steam units for boiler selection products.
Horizontal coal-fired boiler has reasonable structure, high thermal efficiency and fuel saving. SZL series steam boiler adopts heat transfer thread smoke tube, arch tube plate and other new technology, improve flue gas flow rate, make the boiler reliable, energy saving effect is remarkable, high thermal efficiency. The boiler adopts optimized furnace arch, which has strong radiation, stable combustion, good effect and fast heating. The water wall is well made and effectively protects the furnace wall. Advanced performance, long service life. All main welds adopt automatic welding, no repair record, to ensure the welding quality and improve the service life of the boiler. Tubesheet adopts advanced pressing technology to avoid the problem of tubesheet cracking.
The air distribution structure of the coal-fired boiler adopts the dense air chamber with two sides of the air inlet to achieve the uniformity of the transverse air distribution along the grate. And can realize the control of air distribution according to the combustion stage, on both sides of the boiler along the length direction of seven air control doors, and seven ash cleaning handle, furnace personnel can reasonably adjust the air door opening according to the combustion needs. Ash cleaning handle, during the operation of the boiler every shift must be pulled twice, so that the ash falls on the return grate surface, and then by the return grate will leak ash to the front, falling into the ash hopper. Quick loading steam boiler adopts internal dust inertia separation, supplemented by multi – pipe dust collector or bag dust removal equipment.
SZL series coal-fired boiler after the treatment of softening water, through the economizer into the drum, in the upper drum is equipped with water distribution device, the water into the upper drum distribution into the down pipe, and then into the side collection box, through the water wall tube heat absorption, and then back to the upper drum. Another part enters the lower drum and returns to the upper drum through convection bundle heat absorption, and the saturated steam is led out from the main steam tube on the top of the upper drum. Combustion equipment adopts light chain grate, speed regulation adopts frequency conversion speed regulation, easy adjustment, stable operation, also can use reciprocating grate, better adapt to inferior fuel.
Quick loading steam boiler is an assembly type water tube boiler with compact structure, beautiful appearance, suitable for transportation and convenient installation. Boiler working pressure can reach and exceed a certain rated pressure, full load operation design efficiency of 86.1%. Boiler water capacity is large, conducive to power failure protection. Boiler automation degree is high, with pressure, water level pressure relief and other alarm measures as well as a variety of interlocking and automatic control. This series of boiler products are equipped with automatic electric control system and complete monitoring instruments, which can realize automatic water supply, overpressure and overtemperature alarm, advanced remote control function, online monitoring of dosage, fault alarm and other functions.
