Coal Fired Travelling Grate BOILER IN China

Detailed Product Description

 

1.Directly factory,30years experience,professional 2,Chain grate coal fired steam boiler 3.25 years useful lifetime

 

DZL Series Full-Automatic Chain Grate steam boiler  , travelling grate coal fired steam boiler , chain grate coal fired steam boiler

This series boiler is single drum three-return water tube and fire tube steam boiler,Both sides of the wall around the furnace are radiation heating surface,Two  wings of furnace are convective heating surface .The lateral

 of boiler  body  is  shell of  three dimensional shape.

The boiler use  the vaulted tube plate,spiral gas tube to make the thermal efficiency higher and output capacity sufficient

Features:

1 ,the output capacity is sufficient and continuous:Because of adopting the high efficiency heat transmits spiral gas tube,so the real output capacity of boiler is 10%-15% higher than rated.And either output capacity or thermal efficiency will not decline as extended the running time.

2 ,Small size,less investments\:we use efficiency threaded pipe,so hot water boiler that the output water temperature ≤150°c,

with a smaller capacity  steam boiler can cancel the tail heating surface.the height of boiler is less than other coal-fired horizontal steam boiler hwihc has the same capacity.so boiler room will spend much less money

3,No need special protection when power off:The hot water is mixed cycle and the water capacity is large,so the special protection is no need for damage caused by vaporization when power off.

4 ,The efficiency of the boiler is higher:the spiral gas tube is placed inside the boiler,so there will be no cool air entre.This can reduce heat loss and working rate of this boiler is highest.

5 Heating fast:There many spiral gas tubes in the boiler and almost half of the boiler shell can be heated,so the temperature can up soon and the time was short than the water-tube boilers.

6 ,safe and reliable:The special structure and material make the boiler begin with high safety

7,Primordial dust emissions density is low:The volume of the boiler is large and there is a dust separation device,so the primordial dust emissions density will be controlled much lower than the standard allowed

8,Easy to install: The installation charge is little and the installation time is short
