Automatic Feeding horizontal Coal Fired Steam Boiler
DZL series coal biomass fired boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. This furnace structure in reasonable arrangement and high efficiency. This series boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.)
1. Energy-saving and environment-friendly: The adoption of advanced gasified burning technology, cluding the gasified spiral burning chamber and embedded device of second distribution of spiral turbulence, makes the burning of fuels more efficient.
Threaded flues, which are efficient in heat transmission. and reasonable flowing speed of smoke, push thermal efficiency to 85% and higher. The adoption of biomass pellet fuel enableds zero CO emission. With the density of discharged smoke lower than 50mg/m and blackness of exhaustion lower than Ringelmann level, all date has stisfied national environmental protection standard for type-1 areas
2. Low operation cost: Biomass pellet is a new environment-friendly renewable fuel promoted By the government it features hige heationg value, low cost and easy accessibility. The operation cost of the boiler is only 1/ 4 of that of electric boilers and is 1/ 2 lower of that of oil(gas)boilers.
3. Highly automatic: The digital integrated controller enables users to set up auto control so as to control the burning. The operation is as simple as that for oil and gas boilers and it features automatic ignition, material-fending and ash clearing.
4. Safe: Quality auxiliary machines, accessories and auto-control equipment guarantee safe and stable operation.
5. Good appearance: The appearance of the boiler is well-designed and looks beautiful .
