High Temperature Industrial Wood Chip, Rice Husk, Coal Steam Boiler For Edible Oil Extaction And Refinery

high temperature industrial Wood Chip, Rice Husk, Coal Steam Boiler for Edible Oil Extaction and Refinery

DZL type horizontal coal steam boiler

Specification model: 1 -- 20 tons

Thermal efficiency: 85%

Applicable fuel: biomass pellet

Application: medicine, chemical industry, light industry, textile, building materials, breeding, food and beverage, plastic foam, printing washing, rubber processing, paper making, wood processing, hotels, hotels, clothing, etc

DZL type horizontal chain - fired coal fired steam boiler is a horizontal three - return water - fire tube boiler.Two fire tubes are arranged in the pot barrel, and both sides of the furnace chamber are equipped with light tubes and water wall tubes.The combustion equipment adopts light chain grate to realize mechanical addition of biomass, and is equipped with drum and induced draft fan to realize mechanical ventilation.The fuel falls on the grate from the biomass bucket and burns along with the grate, and the flue gas passes through the upper combustion chamber of the rear arch, enters the first bundle to the front smoke box through the upper smoke chamber of the back shed pipe, folds into the second bundle to the back smoke box from the front smoke box, and is introduced into the flue, dust collector and chimney through the induced draft fan, and finally exhausts to the atmosphere.The boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, lead, fan interlock protection.Boiler biomass, slag and other operation mechanization, reduce the labor intensity of workers, supporting a complete set of auxiliary machines.

Performance advantage

1. Adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion.

2.  The steam boiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress.

3.  The spirally corrugated tube strengthen the heat transfer, improve thermal efficiency. The flue gas has the foundation of disturbance, avoid ash depositing in tube.

4. Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.

5.Equipped with reliable boiler auxiliaries,such as international famous brand water pump(Grundfos, CNP), Siemens brand electric control elements, Fleck brand water softemner from USA, etc

6. High level Aumotic control system

The boiler automaticon lelvel is high, the boiler feedwater automatic regulation, high-low water level alarm, low water level interlock protection, fan interlock protection, automatic feeding fuel, automatic water feeding, automatic ash remove function.

FAQ

1.What is the size of furnace door and blower hopper?

Size of furnace door: 
Standard elliptical furnace door:300*800*1500
Blower hopper size:
2 tons conical hopper: 1400*800*1500
4 tons conical hopper: 2200*1400*1500

2.What is the combustion mode of coal/biomass fired boiler?

The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.

3.Material of boiler drum / steel plate / tube.

Boiler drum material: Q245R,carbon steel, executive standard: GB713-2008
Tube material: 20# seamless steel pipe, carbon steel, executive standard: GB3087-2008
Still kettle material: Q345R, alloy steel, executive standard: GB713-2008

4.What is the height of chimney?

The chimney is usually 30m, irrespective of the special circumstances.

5.What are the heat-resistance temperature of grate and furnace?

The heat resistance temperature of grate is related to the grate material, the highest temperature could be as high as 1100℃, and the lower temperature could be 700℃.
