SZL series chain grate boiler is the national patent products of Zhongding Boiler, the patent No. is ZL 2009 2 0089355.7. The traveling grate boiler is horizontal type double drums boiler with high steam quality, the combustion equipment is traveling grate, has the advantages of high automatic degree, high temperature resistances and low fuel leakage. Zhongding boiler takes several breakthroughs on boiler design, such as membrane water cooling wall, low thermal inertia design, and water cooling combustion chamber. The convection heating area increase more than 50%, and by using the light furnace wall, the thermal inertia decrease 70%, to improve thermal efficiency. SZL series traveling grate water tube boiler has the advantages of compact structure, high thermal efficiency, high steam quality, sufficient output, and convenient operation.
ISO 9001, CE, BV, SGS, ASME
Rice husk, wood chips, bagasse, straw, and other biomass fuels.
1. The boiler boiler adopts membrane water cooling wall structurer, the boiler is full sealing, reduce heat loss, improve boiler efficiency.
2. Whole membrane water cooling combustion chamber and inverted "α" arch furnace technology achieve high combustion efficiency, high output.
3. Extended length of the grate, extended the coal burning time, improved the boiler thermal efficiency.
4. Light furnace wall structure reduce heating loss, thermal inertia decrease 70%, furnace heat up fast, boiler start-up and shut down quickly.
5. Anti-coking heater design, remove the side sealing steel, avoid the problem of grate stuck and uneven air distribution for combustion.
6. Adopt light rail I-beam for the rail under the grate, abrasion resistance and difficult for deformation, improve the reliability of boiler operation.
The chain grate is 500~1000mm longer than others, lengthen the fuel combustion time, improve combustion efficiency.
We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.
We adopt 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.
