SZL series biomass boiler is a double boiler with longitudinal arrangement of water tube boiler with short installation period and low installation cost. It is one of the most popular boilers in the market. Biomass steam boiler performance is superior, the water circulation circuit is reasonably designed, the boiler drip tube is set outside the furnace without heating to ensure a reasonable circulation rate. The series boiler tubes are not easy to scale, and the boiler operates safely and reliably.
The combustion chamber of biomass boiler is mainly composed of water-cooled wall tubes and the upper boiler tube arranged around the body. The convection heating surface consists of a bundle of convection tubes closely arranged between the boiler tubes, and the two convection returns are horizontally arranged. The tail of the boiler is equipped with a separate energy-saving device and two ash dropping ports and two inspection holes, which are conducive to inspection, maintenance and ash cleaning. This series of steam boiler has a large heat receiving area and sufficient output power. Low exhaust gas temperature and high thermal efficiency. Boiler operation is safe and reliable, with multiple pressure and water shortage interlock protection devices.
Biomass steam boiler performance is outstanding, with double boiler tube vertical arrangement horizontal water tube chain grate boiler, compact structure, beautiful appearance. It covers a small area. The upper (middle) and lower parts are ex-factory and assembled on site. The installation cycle is short and the cost is low. Boiler room can be arranged in a single layer, saving capital expenditure. Equipped with all kinds of dust removal equipment, the smoke and dust emission can meet the environmental protection requirements of different regions. Reasonable air distribution, independent adjustment of gas chamber, small air leakage, good combustion conditions. Matching front and rear arches are used to accommodate various fuels.
This series of biomass fired steam boiler has high automation level, safe and stable operation, strong fuel applicability and high standard of soot emission. The furnace is followed by a combustion chamber with convection tube bundle and a coal saver at the end. Flue gas enters the tail flue through the furnace chamber, combustion chamber, convection tube bundle and coal saver, and is discharged into the atmosphere through dust collector, induced draft fan and chimney. The front wall is equipped with secondary air, controlled by valve, which is put into use when burning biomass fuel to enhance the combustion and make the fuel burn fully and improve the combustion efficiency. Higher inlet is used to meet the demand for biomass fuel.
This series of industrial boilers are made of high-efficiency insulation materials, with low surface temperature of the boiler and low heat loss. Manufacturing is strictly in accordance with the standard production, all pressurized parts are made of high quality boiler steel, and each boiler must pass strict inspection and testing before leaving the factory. Including water pressure test and X-ray inspection, manhole, inspection door, fireproof hole, etc. The boiler has the characteristics of energy saving, environmental protection and easy installation.
The biomass steam boiler has outstanding performance, reasonable shape design, beautiful and generous appearance, the arch of the furnace has been continuously improved, the sturdiness has increased, and the combustion is more stable. The above is the SZL series biomass boiler of Zhongzheng Boiler, which is fully proved in the users’ use. Therefore, this type of boiler is well received by the majority of users and widely used by them.
