DZL series steam boiler to strengthen the heat transfer: the boiler adopts the threaded smoke pipe, the heat transfer coefficient of the threaded smoke pipe is twice as much as the light pipe, and under the guarantee of high heat transfer coefficient, the optimization design, so that the flow resistance is appropriate, no ash, small wear, high strength, anti-fatigue. The DZL series coal fired boilers capacity can be 2-20t/h, and the operation is stable and reliable. Welcome to consult and purchase.

Thread of this series of coal-fired boiler smoke tube soot cleaning ability, threaded pipe load half of flue gas flow rate is still can be in more than 8 m/s, more than in the velocity of threaded pipe produced by the ash removal ability (rotation of high speed air flow will be lower than half load set grey swept away), this is not set gray phenomenon, make the type boiler in a constant output unchanged, the efficiency in the operation of all the year round.

Coal fired boilers capacity have large and can be customized according to user needs, running smoothly and reliably. The boiler is a variable furnace arch structure of low nitrogen oxide boiler, including the front, middle and back three sections of the air chamber, chain grate, by the front and back arch composition of the combined arch. At the bottom of the pot room arrangement in the wind and the wind chamber and achieve segmented with the wind, before and after the period of the wind room decorate a grate, above the furnace front before installing upward sloping arch tunnel, after the furnace after installation tilt of the arch, the boiler fuel and combustion characteristic, make to adapt fuel boiler type, degree of fuel is good, the effect of low pollution emissions.

This series of steam boiler calorific value is high, combustion efficiency can reach more than 90%. The boiler is equipped with blower, induced draft fan for mechanical ventilation, and equipped with slag discharging machine to realize automatic slag discharging. The whole structure of DZL series boiler is single cylinder longitudinal chain grate boiler, three return water and fire tube structure, simple structure and mature technology. Coal-fired steam boiler adopts automatic operation, on the basis of saving labor, automatic feeding, with higher productivity.

This series of boilers have boiler steam pressure automatic regulation system, the system control system into the working state, to meet the necessary conditions of combustion, the boiler steam pressure is higher than or equal to the set pressure limit, the control system output stop signal. Until it stops burning. When the coal fired steam boiler system is working normally, start the feed water pump, the water pump works, the water level differential pressure transmitter detects the water level signal, and keeps the water level of the drum stable. In order to ensure the quality of boiler steam.

Coal fired boilers capacity have large, reasonable structure design and safe and reliable operation. DZL series steam boiler steel plate blanking, ring, drum, tube plate drilling and other key processing technologies adopt advanced numerical control processing, reduce the assembly stress, prolong the service life of the boiler. Steel pipe cutting, screw pipe pressing, convection pipe processing using advanced numerical control technology.
