2. Product Introduction

(1) Powdered coal boiler

1.The high efficiency coal boiler system(patent No. ZL200520002170.X)designed by Beijing Research

institute of Coal Chemistry(the China Coal Research institute) includes 1.0~30t/h steam boiler and 0.5~

21MW hot water boiler.Their efficiency is high.and the waste emission can be highly controlled. the inve

stment is moderate.the control is simply. the running cost is low.The structure characters are as following.

 Hetero-gallbladder. so the burning temperature is low and high efficient,it is easy to discharge the ash. 
2. The waste gas is dedusted with hop-pocket,there is almost no visible particle released to the air,and the 
emission is much lower than the national requirement. Recur to the self-desulfur technique,the sulfut content 
of the waste gas is much lower than much lower than the national requirement as well as the Beijing local 
requirement too. 
3.The boiler is equipped with auto control system,so,it can be auto controlled and adjusted,the parameter 
4. Can be recorded continuously. We botain a big breakthrough on the auto control of coal-fiting boiler. 
5.The boiler needs a small installing area,all the operations of milling,convering,feeding,buring,dedusting 
are closed,so,the control environment is good.
