Product Description
Introduction
The vertical type rice husk fired steam boiler is a small capacity boiler with horizontal water tubes, it fits for the small industries, and has the advantages of compact structure, small footprint, and save infrastructure cost. Flue gas is brushing the inner wall of furnace and water tubes, for radiation heat transfer and convection heat transfer, the grate and lower part of furnace is radiation heating area, the horizontal water tubes and upper part of furnace is convection heating area.
 
Except rice husk, the fuel could also be wood chips, rice hull, bagasse, straw, peanut shell, mustard stalk, cotton stalk, coconut shell, and waste cloth, etc. biomass particle diameter should be 6-10 mm, length should be 25-50mm, and water content should be less than 15%. The source of solid biomass fired boiler fuel is widespread, has the advantages of low cost, environmental friendly (sulfur content<0.06%, and zero CO2 emission), energy saving, and high combustion efficiency (>90%).
 
Compare with coal fired boiler, the biomass boiler has the different characteristics: 

1. The furnace combustion space is larger, to fit for the high-volatility biomass fuel.
2. Economizer and air preheater could be arranged at the tail of biler to improve the thermal efficiency.
3. Based on different biomass solid fuel, Zhongding Boiler could design the specific boiler individually.

 

Combustion Process

The vertical type coal fired steam boiler adopts the general combustion techniques, the combustion equipment is moving grate, coal or biomass fuel was fed by workers manually. after buring in the moving grate, the exhaust gas passes through the horizontal water tubes, and the small carbon black and dust fall down onto the grate for reburning, and then the exhaust gas is released to the atmosphere through the chimney.
Application
The small vertical type coal fired boiler is widely used for industrial production, such as textile industry, food industry, sugar mill, paper industry, chemical industry, garment industry, etc. Otherwise, it could used in hospital, school, hotel, etc.
Advantage

1.  High Quality

\


1) Zhongding Boiler owns a professional design engineer team, before manufacturing, every boiler design drawing will be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
2) To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
3) To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.
4) Nondestructive testing will be done to ensure the welding quality, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
5) Hydrostatic test will be done to ensure the leakproofness and strength of boiler pressure parts, generally, the testing pressure is 12.5 times of rated working pressure.
6) All the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international quality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.
 
2. Advanced Technology and Structure

\


3. Professional Installation and After-sale Team
1) Professional engineer installation team offer the door to door installation and after sale service. The boilers will operate smoothly and safety, and you will get them without worries.
