Rice Husk Steam Boiler Introduction
The rice husk steam boiler is a single-tube water tube and fire tube boiler, and the combustion equipment is a chain grate. The water wall pipes on the left and right sides of the furnace are radiant heating zones. The two wings of the furnace and the spiral fire tube in the rotating drum are convection heating zones. The rice husk hot water boiler adopts the upper drum, and the water wall tube is symmetrically arranged with the machine head. The drum is welded and assembled by the cylinder body and the front and rear tube plates. This kind of furnace has reasonable structure layout and high efficiency.
This rice husk boiler adopts scientific achievements such as arched tube sheets and spiral fire tubes to solve the problems of tube sheet cracks, water wall tube bursts, low efficiency, insufficient output, and poor adaptability to different biomass fuels. Heat transfer .
In addition to rice husk, the husk fired boiler can also burn other biomass fuels, such as wood chips, bagasse, rice straw, coconut husk, cottonseed, corn cobs, peanut husks, waste cloth, etc. To avoid coking and improve combustion efficiency, the unique dual secondary air design is adopted to improve the use conditions of biomass fuel.
Rice Husk Boiler Features
1) The small scale chain grate boiler could resist the temperature as high as 1200℃, long working life.
2) The chain grate has a low biomass fuel leakage because of the small gap.
3) Mechanized feed, high automatic degree, decrease labor cost.
4) Convenient for maintenance, it could be done without boiler shut down.
5) Based on customers’ requirement and fuel characteristics, the grate could be designed as reciprocal grate.
Husk Fired Boiler Advantages
1.High Quality Assurance
(1) There is a professional design engineer team, before manufacturing, every boiler design drawing have to 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) The welding quality will be further examined during boiler manufacturing, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
(5) To ensure the boiler quality, the leakproofness and strength of pressure parts will be tested. The hydrostatic test is done to make sure there are no water drop or water mist leakage appear on steal wall or welding joint, no water leakage appear at the place of expansion, and no obvious residual deformation and abnormal situation.
(6) To ensure no problems before boiler delivery, all the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international uality 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. Satety Assurance
(1) Reliable boiler auxiliaries and multiple safety protection devices, such as water level alarm, and safety valve, etc
(2) Full automatic interlock protection program, has the protection function of water shortage, over pressure, over temperature, gas leakage, flame out, electric leakage, and phrase-lacking or overloading of motor, etc.
(3) Excellent and complete instrument system and PLC full automatic intelligent control system. The boiler could operate automatically after starting, the whole system could be controlled by the touch screen, operate conveniently. The internal wiring and elements are installed clean and tidy, to ensure the safe operation.
3. High Efficiency Assurance
(1) Adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion, and the boiler could absorb the thermal expansion effectively. The large diameter boiler drum increases the radiant heating surface, to ensure the high thermal efficiency.
(2) The spirally corrugated tube strengthen the disturbance of flue gas, high heat transfer efficiency.
(3) The boiler shell use aluminium silicate board for heat preservation, the thickness of board id 8cm, high thermal shielding efficiency buy low heat loss, to increase the boiler thermal efficiency.
(4) The furnace wall was poured entirely by the heat-resistance concrete and high-temperature-resistance refractory brick, excellent leakproofness, no air leakage, low heat loss.
(5) By equipping with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase the thermal efficiency.
(6) Adopts variable frequency water supply, air supply and air induced improve boiler operate efficiency.
4. 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.
(2) 24 hours hot-line to solve your problems, and offer the professional technical supports and after sale service in time to all over the world.
5. Convenient Maintenance
(1) The chain grate is convenient for maintenance, it could be done without boiler shut down.
(2) There are manhole, head hole, and special hand hole on the boiler, convenient for boiler internal installation, inspection and clean.
