Zhongding DZL boiler is the new type fast-assembly coal/biomass boiler, this is national patent product, and the patent number is 200920088278.3. The boiler equipped with water cooling arch and two-wing flue. Compare with the other boilers with same parameters, it has more compact structure, more reliable operation, smaller volume, faster output and higher thermal efficiency.
ISO9001, CE, SGS, ASMEII
II class bituminous coal, meager coal, anthracite coal
1. The fore-and-aft arch of the boiler utilizes the patent technique: the horizontal water-cooling pipe irrigates the whole water-cooling arch structure. It increases the heating area, has the function of heat insulating arch.
2. The boiler employs the structure of water-cooling side contact-seal. The design is advanced and reasonable, it replaces the traditional way for side seal with iron, avoids the problems of grate stucked by cast iron seal and side seal burnout because of air leakage.
3. The design of two-wings flue makes the flue gas access flue gas box from the back smoothly, increases the flue gas temperature in the high temperature tube plate, avoids the tube plate crack.
4. The drum employs single-return screwed pipe, improves the efficiency of heat diffusion, and avoids dust gathered in flue gas tube by taking advantage of screwed pipe’s ability of gas clean automatically.
The chain grate is 500~1000mm longer than others, improve combustion efficiency. The grate has small fuel leakage, has long working life.
We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.
The boiler is equipped with aluminum alloy fin tubes, its heating transfer area is 2-10 times larger than the bare tube, has a good heating transfer and mechanical property.
We adopts the stainless vertical pump with low noise, stainless impeller and pump body.
Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.
It is fully automatic and free debugging. We adopts PE material for salt tank body, it has hard texture and it is easy to move, anti-shock, and no leakage.
Zhongding Boiler pay more attention to the boiler quality from raw material to producing process.
