Product Description

1.Four turnhaul heating 

2.unique thermal insulation technical;
3.The heating surface consists of the double layer coils so as to lay out enough heating area ;
4.Ceiling tube reduce s the resistance off the medium inside the heater,so as to ensure rhe safer usage of the heat transfer oils.
5.The ceiling coil on the top of the radiant heating surface can protect the furnace top better and prevent it from being burned out.
Main Features of Environmental Protection 6 tph automatic coal boiler
1.The overall layout is compact, covers a small area. Only single storey layout is needed for the boiler room, low cost on infrastructure construction, convenient for transportation, and short installation period.
2.Using spirally corrugated tubes, strengthen the disturbance of flue gas, high heat transfer efficiency.
3.Reasonable design, safe and reliable operation, flat fire bed, and high thermal efficiency.
4.Complete auxiliaries, mechanized coaling and slag tapping, convenient operation.
5.Use chain grate, low coal leakage, good ventilation, wide adaptability of different coals.
6.The boiler shell use aluminium silicate board for heat preservation, low heat loss.
7.Equipped PLC full automatic intelligent control system, operate automatically.
8.Full automatic interlock protection program, has the protection function of water shortage, over pressure, over temperature, gas leakage, flame out, and electric leakage, etc.
9.By equipping with economizer, make full use of flue gas heat, increase the thermal efficiency.

Machine Parts

Name: chain grate
Brand: Zhitong
Original: China

 The scale chain grate boiler could resist the temperature as high as 1200℃, long working life. It has a low coal leakage because of the small gap. High automatic degree, decrease labor cost. Convenient for maintenance, it could be done without boiler shut down.


Machine Parts

Name: Economizer 
Brand: Siemen/Baltur
Original: china 

Economizer is the boiler tail flue in the boiler feed water heated to the steam pressure under the saturated water heating surface, because it absorbs relatively low temperature flue gas, reducing the smoke exhaust gas temperature, saving energy, improve the efficiency

Main Parts

Name: Threaded Smoke Pipe
Brand: Zhitong
Original: China

The boiler use spirally corrugated tube, the thermal transfer efficiency is high. The texture of it is 20# steel, it belongs to low-carbon steel, has high tenacity.

Main Parts

Name:  Blower 

Brand: Zhitong
Original: China
 Blowers are volumetric blowers. When used, with the pressure changes, the flow of change is very small. But the flow changes with the speed. Safe operation, long service life is a major feature of blower products.

Can be customized according to customer requirements


Q: What are the available fuel for the oil gas fired boiler?

A: Oil gas fired boiler could burn both liquid fuel and gaseous fuel. The liquid fuel could be heavy oil, light oil, diesel, furnace oil, bunker oil, LPG (liquefied petroleum gas), etc. The gaseous fuel could be natural gas, city gas, bio-gas, etc.

Q: Whether the boiler can burn dual fuel or multi-fuel?

A: ZT boiler have oil burner, gas burner, and oil&gas dual fuel burner, we can offer the specific burner based on customers' requirement.

Q: What is the advantages of fire tube boiler?

A: This fire tube boiler has compact structure and convenient operation, strong load adaptability, lower water quality requirement, and the failure rate of it is lower than 0.1!

Q: What is the inlet pressure of gas burner?

A: The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 18~20KPa.

Q: What is the inlet pressure of gas burner?

A: Required environment: 20℃, 1013.25mbar.

When select the model, the environment condition (temperature and elevation) should be considered, correct the burner output curve when the environment condition is different
