The fully-automatic chain biomass steam boiler adopts a double-boiler vertical arrangement, and the combustion method is a chain grate, which uses biomass shaped solid fuel. The rice husk steam boiler adopts membrane water-cooled wall structure on both sides of the furnace. The water wall pipes on the front and back walls of the furnace extend down to the upper part of the grate to form front and rear arches, which not only increase the sealing performance of the boiler, but also increase the furnace volume and heating surface, and at the same time strengthen the strength of the back arch.

Behind the furnace of this series of steam boilers is a combustion chamber, a convection tube bundle, and an economizer at the end. The flue gas enters the tail flue through the furnace, the combustion chamber, the convection tube bundle, and the economizer, and is discharged into the atmosphere through the dust collector, induced draft fan, and chimney. The front wall is equipped with secondary air, which is controlled by a valve, and is put into use when biomass fuel is used to intensify the combustion, so that the fuel is fully burned out, and the combustion efficiency is improved. A higher feed inlet is adopted to meet the demand for biomass fuel.

Automated rice husk fired boilers are widely used in the food industry, chemical industry, packaging industry, pharmaceutical industry, biological equipment industry, washing and ironing, concrete curing, cleaning and other industries. The rice husk steam boiler runs ultra-quiet 80dB and has an ultra-long operating life of 20 years. This series of boilers have full and thorough fuel combustion, low exhaust gas temperature, high thermal efficiency, and can save 5-10% of operating costs. After the biomass boiler fuel is burned in the furnace, the flue gas enters the independent cyclone burn-out chamber for secondary combustion, and the fuel burns fully and thoroughly, which improves the thermal efficiency.

The biomass steam boiler can automatically control the fuel delivery volume according to the amount of heat used, isolate the flame and fuel, and prevent backfire. The boiler is equipped with a primary fan and a secondary fan, and the air distribution ratio is reasonably arranged to ensure sufficient combustion to avoid coking and prolong the service life of the boiler. The end of the SZL series steam boiler is equipped with an economizer, and an air preheater can also be arranged according to user needs. The boiler is equipped with an automatic ash removal device, which can remove ash deposits on the heating surface of the boiler in time to ensure efficient and stable operation of the boiler. A higher feed inlet is adopted to meet the demand for biomass fuel.

The specific operation of the rice husk steam boiler should be carried out in accordance with the product manual to ensure the safety of operators and equipment. This series of steam boilers are environmentally friendly and save fuel. The boiler automatically feeds and discharges slag, and the blower and induced draft fan are adjusted by frequency conversion. The boiler runs fully automatically, the fuel quantity can be adjusted automatically according to the load change, and the steam output is stable. This type of boiler effectively reduces energy consumption, reduces carbon dioxide, sulfur dioxide and nitrogen oxide emissions, and improves the environment.
