steam boiler

in aerated block production linethe selection of steam boiler we generally chooseSZL series steam boiler, double drum, fast heating, high efficiency of gas supply equipment.

SZL assembled water tube steam boiler is the performance characteristics of double drum vertical chain grate boiler:

(1) The advantages of this boiler absorbing fast-loading boiler: the upper large piece consists of the boiler body, the upper furnace wall and the insulation layer; The lower large piece consists of a chain grate and a coal hopper. After the two large pieces are closed at the construction site, they can be put into operation only by building the lower furnace wall. Therefore, the site installation is convenient, the cycle is short, and the cost is low. The boiler has the advantages of compact structure, small occupied area, beautiful appearance, and the boiler room only needs a single layer layout, so the civil engineering investment is small.

(2) The boiler is easy to operate, stable in operation, fast in heating and boosting, sufficient in output, and suitable for a wide range of coal types.

(3) Complete auxiliary equipment, drum, induced draft fan, water pump, dust collector, etc. can meet the boiler load requirements. The grate adopts a stepless speed change device, with a wide speed range and convenient speed regulation.

(4) The boiler is equipped with a relatively complete thermal monitoring electronic control console. The opening degree of the induced draft fan and the speed of the grate can be operated according to needs. The boiler pressure is equipped with overpressure protection device, high and low water level alarm and extremely low water level interlocking device to cut off the blower and stop the grate rotation.

(5) The boiler air supply system adopts a warehouse-type double-sided air supply device. Each air chamber can be adjusted independently, with small air leakage and strong adjustability, which can better adapt to the combustion characteristics of the chain furnace.

(6) The front and rear arches of the boiler are very reasonable, which is conducive to the full mixing and combustion of the airflow. The front arch has a water cooling device to ensure that the coal gate and the front furnace panel will not burn out.

(7) Coal has strong adaptability, heat quality ≥ 3800KcaI/Kg,Vr≥ 20% can stably burn and reach rated pressure.

(8) The boiler can realize automatic continuous water supply according to the load.

(9) The boiler has high thermal efficiency, low exhaust gas temperature and certain overload capacity.
