1. 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.

Product Features of JRL Series Hot-biast Stove JRL series hot-blast stove is a new designed stove

absorbing the merits of SZL series coal fired boiler.This series of product is a kind of heating equipment

by mechanical adding coal,mechanical deslagging and chain fire grate firing.At the same time,it can save

the labor of the stoker.Most parts of the JRL stove are built with refractory,so,it has a long lifespan.And the

thermal effciency is up to 80%,it can be widely used in chemical industry, food service industry and building

industry.

3,The heat effciency can keep on optional level under each load.

4,Eletricity,water and investment can be saved

(5)SZL Series Package Hot-water Boiler

1,Orogonal horizontal tourbilion burn locule is applied on the boiler,which can improve thermal

efficiency and lower waste concentration released notably.Smoke emission concentra-

tion is less than 100mg/m3,smoke blackness is less than Ringelmann I level.It can be

used for first class regions of the state.

2,Thermal efficiency is high,and the thermal efficiency of all kinds of boiler exceed mi-

niistry-issued standards over 5%.

3,Water-tube boiler has a rational structure,which runs safely and reliably,and it has a

long life-span.

4,machining conical surface sealing stucture is applied to air distribution device,avera-

ge windpipe stucture is adopted in the wind room.This technology is protected by nati-

onal patent.

5,the boiler is widely suitable for fule,such as bituminous coal class II and classIII.

(6)DZL Series Package Hot-water and Steam boiler

1,The crack of pipes and plates under high temperature can be prevented by using single backhaul

solenoid,arch plate,aerofoil flue and elastomer shell taking the place of rigid shell.

2,The rational designed circulation loop prevents the base heating and bubbling.Backwater

ejecting can improve the reliability of circular water, get rid of the pipes slagging and lrt the

stove run orderly.

3,Good smoke prevention and dust control,the dust is inertial separated from the gas in thestove.

4,Small stove by optimize design and the price of boiler room can be decrease 30%.

5,Good firing ,itcan add coal and deslag automatically,so,it can save the stoker"s labor.
