The design and manufacture of coal fired boilers shall be strictly carried out in accordance with the requirements of general technical conditions and manufacturing technical conditions. The furnace body is equipped with pressure gauge, safety valve, water level gauge and other instrument valves, the pressure gauge shows the pressure of the boiler, the user can know well. The safety valve of coal-fired steam boilers opens automatically when the boiler reaches a certain pressure, and depressurizes the gas to ensure the operation of the boiler.
SZL series steam boilers using a single cylinder longitudinal arrangement of three return water and fire tube type structure, furnace on both sides covered with light tube water wall tube, design structure is reasonable and compact; The heating area is large, the flue gas flow is long, the heat transfer effect is good, the smoke exhaust temperature is low, so the thermal efficiency is high, the operation cost is low, the use is more economical. Randomly equipped with instrumentation valves and other safety accessories, complete sets of equipment safe and durable, customer satisfaction. Users can choose the boiler softening water device, adding water treatment, furnace bladder less scale, boiler safety and energy saving.
Coal-fired steam boilers use efficient insulation materials, boiler surface temperature is low, heat dissipation loss can be ignored. Strictly according to the specifications and standards of production, all pressure parts are made of high quality boiler steel. Before leaving the factory, every boiler has to go through strict inspection and testing, including hydraulic test and X-ray inspection. Set with manhole, inspection door, fire hole, etc., maintenance is very convenient.
This series of steam boilers are double tube longitudinal type water pipe chain grate or reciprocating grate boilers with small heating area, sufficient output and strong load regulation ability. This series of boiler furnace volume is large, has the good smoke dust settlement function, convection tube bundle adopts the “S” type structure, the infection effect is good, the heat efficiency is high, the dust removal effect is good, the dust removal is convenient. The boiler drum is arranged longitudinally along the center of the boiler. The boiler drum and the water-wall pipe on both sides form the radiant heating surface of the furnace, and the tube bundle between the upper and lower drum forms the convective heating surface. The fuel has wide adaptability and can burn the coal with higher ash content.
Coal-fired steam boilers drum volume is large, the internal device is complete, the steam quality is good. It is the product of boiler selection for medium and small steam units. Chain grate air into the air bin, each air bin air volume independent regulation, stepless grate speed regulation. The boiler has the advantages of compact structure, small footprint and short installation cycle. The boiler adopts high quality insulation material and special construction technology, so the heat loss is small. Special design of grate and furnace arch, independent adjustment of air volume, uniform and sufficient coal combustion, wide adaptability of coal types.
