Kingthai DZL Series Coal Fired wood industrial Boiler in Nepal
Kingthai DZL coal fired chain grate boiler realizes almost zero pollution with the use of special dust collector solution (bag dust collector, double towers desulfurization, etc.), it is honored as Chinese famous brand. This series boiler is single drum horizontal type shell boiler with three-pass structure, the combustion equipment is chain grate (small scale flaker is available), has the advantages of feed mechanically, strong adaptability of different fuels, low coal leakage, and convenient maintenance. The fuel is coal, the diameter should be 6-25mm, and ash content should be less than 32.4%.
1) The small scale chain grate boiler could resist the temperature as high as 1200℃, long working life.
2) The chain grate has a low coal leakage because of the small gap.
3) High automatic degree, decrease labor cost.
4) Convenient for maintenance, it could be done without boiler shut down.
5) Based on customers' requirement and fuel characteristics, the grate could be designed as small scale grate, chain belt grate, bar grate, etc.
2. Kingthai Boiler-High thermal efficiency
1)The spirally corrugated tube strengthen the heat transfer, improve thermal efficiency. The flue gas has the foundation of disturbance, avoid ash depositing in tube.
2)The furnace wall was poured entirely by the heat-resistance concrete and high-temperature-resistance refractory brick, and the boiler shell use aluminium silicate board for heat preservation, low heat loss.
3) Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.
3. Kingthai Boiler-Avoid bulging
The riser tube bundle under the drum, remove the dead water region at the bottom of drum, sludge is not easy for depositing, the high temperature area of drum has better cooling, prevent bulging.
4. Kingthai Boiler-Avoid tube plate cracking
1) The boiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress, solves the problems of tube plate cracking.
2) Arrange two sides gas duct in drum, the smoke gas could enter into the front smoke chamber smoothly, the temperature of tube plate is lower than 600℃, avoid cracking leaded by high temperature.
5. Kingthai Boiler-Sufficient output
Adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion, and the boiler could absorb the thermal expansion effectively. The large diameter boiler drum increases the radiant heating surface, to ensure the sufficient output.
6. Kingthai Boiler-Environmental protection
1) The splayed wall and smoke outlet have the function of dust removal, decrease the concentration of smoke emission.
2) The moving grate boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement
Kingthai SZL series water-cooling arch and membrane water-cooling wall shop-assemble boiler is a new type water tubes shop-assemble boiler which is developed by Kingthai Boiler independently based on the features of field assemble boiler arch. For the first time in China, the technology of water-cooling arch and membrane water-cooling wall are smartly used in this series. The technology is in the leading level in the world. It has the features of wide range of load adjusting, can be adjusted to many kinds of coal, thus it is awarded the best design of this kind of boilers.
A wood industrial in Nepal purchased two sets of high efficiency and energy saving chain grate boilers from Kingthai. the chain grate boiler is widely used in industrial heating, power station, public heating. 10 tons chain grate steam boiler and 7MW chain grate hot water boiler are used for heat supplying, fully meeting the demand of the heating of the wood industrial factory.
