Xineng is liable for the unbiased design and style of the biomass fired steam boiler, which converts biomass chemical energy into the heat energy necessary in generation procedures, heating of gear and basic warmth provide and manufacturing.

This steam boiler is extensively employed in energy stations, chemical crops, textile mills, printing and dyeing mills and meals processing vegetation.

  • Foodstuff sector: The steam can be utilized for cleaning, as nicely as heating, drying or disinfecting food.
  • Spinning, printing and dying sector: employed for dying, rinsing and shaping of cloth.
  • Biological drugs sector: used for heating response kettles, condensation reaction, exchanging warmth and disinfecting of chemical response systems.
  • Clinic: used for disinfecting, heating, and air conditioning.
  • Petrochemical Sector: used for heating oil in order to enhance liquidity.
  • Wood home furniture market: used for drying wooden, brick and other supplies.
  • Papermaking business: High force steam is utilised to drive electricity generation. Soon after decompressing, the steam is employed for drying, and the final of the low-force steam is utilised for ink elimination, pulping or paper creation.
  • Tobacco business: provide heat for generating pipe tobacco and baking.

Production Procedure Attribute

1. Boiler substance: seamless steel pipe
two. Welding process: Argon arc welding and radiographic screening
3. Bending shaping: The tube is shaped soon after the bending process in the pipe bending equipment in purchase to make certain the coil outline dimension precision and make sure it meets GB/T17410 expectations.
4. Water strain testing: After shaping, the h2o force test for the tube is carried out just before the boiler leaves the manufacturing facility.


1. There are distinct kinds of biomass fuel: Straw, rice straw, wood, palm shell, bark and other waste crops can be utilised as fuel. They are clean and environmentally helpful, function a substantial combustion performance, and can be very easily transported.
2. In comparison to coal, organic fuel, and oil, biomass gas is not only much less high-priced, but also has exceptional characteristics for power conservation, environmental security and gasoline regeneration.
3. We have an A grade manufacturing license, and the ASME production qualification S U stamp.

System Composition

The industrial boiler is a normal circulation boiler that is divided into two parts. The upper location is the boiler heated area, with the reduce element consisting of the grate. The conclude of the boiler is equipped with an economizer and air-preheating system. The boiler also features a water circulation system, flue gasoline method, ash system and blowing program.

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

two. Grate
The boiler employs a chain grate with wind blowing from the base. There are six unbiased wind chambers in the grate, which can be altered based on user combustion problems in get to save electric power.

three. Economizer
The economizer is placed on the tail conclude of the boiler, and is employed to recuperate residual warmth from the flue gas. When the temperature of the exhaust gas is also high, the economizer will decrease the temperature and conserve gas.

4. Air for every-heater
The air pre-heater can heat the air before it enters the boiler, and therefore, boost the boiler’s combustion effectiveness.

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

six. Ash program

Following fuel burning, the resulting ash will be discharged using a slag extractor at the finish of the grate. Ash that is not quickly discharged will tumble into the entrance ash bucket with the chain grate operating. This indicates consumers do require to frequently clean the grate.
