Xineng is liable for the unbiased layout of the biomass fired steam boiler, which converts biomass chemical energy into the heat vitality needed in creation processes, heating of tools and basic heat supply and manufacturing.

This steam boiler is extensively utilised in electricity stations, chemical plants, textile mills, printing and dyeing mills and foods processing vegetation.

  • Food market: The steam can be utilized for cleaning, as nicely as heating, drying or disinfecting foodstuff.
  • Spinning, printing and dying market: utilised for dying, rinsing and shaping of cloth.
  • Organic medicine business: used for heating reaction kettles, condensation response, exchanging heat and disinfecting of chemical response techniques.
  • Hospital: used for disinfecting, heating, and air conditioning.
  • Petrochemical Industry: used for heating oil in purchase to boost liquidity.
  • Wood household furniture business: used for drying wood, brick and other resources.
  • Papermaking business: High stress steam is employed to travel power technology. After decompressing, the steam is employed for drying, and the last of the reduced-pressure steam is utilised for ink removing, pulping or paper generation.
  • Tobacco industry: provide warmth for creating pipe tobacco and baking.

Producing Process Characteristic

1. Boiler material: seamless metal pipe
2. Welding procedure: Argon arc welding and radiographic screening
3. Bending shaping: The tube is formed soon after the bending procedure in the pipe bending device in get to make certain the coil define dimension precision and make certain it meets GB/T17410 specifications.
four. Water pressure screening: After shaping, the drinking water strain examination for the tube is carried out prior to the boiler leaves the manufacturing unit.


one. There are distinct sorts of biomass gas: Straw, rice straw, wooden, palm shell, bark and other squander crops can be utilised as fuel. They are clean and environmentally friendly, attribute a high combustion efficiency, and can be effortlessly transported.
two. In comparison to coal, natural fuel, and oil, biomass fuel is not only less pricey, but also has outstanding attributes for vitality conservation, environmental security and gasoline regeneration.
three. We have an A grade producing license, and the ASME manufacturing qualification S U stamp.

Technique Composition

The industrial boiler is a normal circulation boiler that is divided into 2 areas. The higher location is the boiler heated surface area, with the reduce portion consisting of the grate. The end of the boiler is geared up with an economizer and air-preheating system. The boiler also features a h2o circulation method, flue gas technique, ash program and blowing system.

1. Boiler heated surface
The boiler heated surface is composed of the steam drum, h2o drum, header, h2o wall and convection tube bundle. The h2o drum is also outfitted with a sewage system.

2. Grate
The boiler makes use of a chain grate with wind blowing from the base. There are six unbiased wind chambers in the grate, which can be modified primarily based on user combustion conditions in order to help save electrical energy.

3. Economizer
The economizer is put on the tail conclude of the boiler, and is employed to recuperate residual heat from the flue gas. When the temperature of the exhaust gasoline is also substantial, the economizer will lessen the temperature and conserve gasoline.

4. Air for every-heater
The air pre-heater can warmth the air prior to it enters the boiler, and hence, improve the boiler’s combustion efficiency.

5. Drinking water circulation system
Water resource-pump-economizer-drum-downcomer– h2o drum– riser tube– steam drum– steam outlet

6. Ash technique

Soon after gasoline burning, the resulting ash will be discharged utilizing a slag extractor at the finish of the grate. Ash that is not rapidly discharged will fall into the front ash bucket with the chain grate managing. This signifies end users do require to frequently thoroughly clean the grate.
