Eco-friendly SZL commerical hot water boiler 2.8-29MW with horizontal type for paper and textile factory
The SZL series commerical hot water boiler adopts a double drum vertical structure, and the combustion equipment is a light chain grate. The specific working process of the hot water boiler is briefly described as follows: the front part of the boiler body is a combustion chamber, which is composed of a water-cooled wall, a drum and a header, and the purpose is to absorb the radiant heat of the furnace; at the rear of the boiler body, a convection tube bundle, The convection tube bundle is evenly arranged between the upper and lower drums, and the high-temperature flue gas after combustion passes through the convection heating surface, is sent to the separately arranged economizer, and finally enters the dust collector and is discharged through the chimney.
Due to the large size of the SZLcommerical hot water boiler. Therefore, for equipment with a rated output of 4-6t/h, a quick-fit structure is adopted. After being completely assembled in the factory, the hot water boiler with rated power of 6~35t/h is divided into two parts: the heating surface of the body and the burning equipment.
Technical advantages:
1. Strictly control the quality. In the boiler production process, important processes such as steel plate cutting, coiling, forming, drilling, etc. are strictly controlled to ensure the production quality of the boiler.
2. Commerical hot water boiler weld welding adopts advanced welding technology, and carries out X-ray flaw detection on key stress points to eliminate defective products.
3. In the commerical hot water boiler design process, the core patent technology of several companies is adopted to make the thermal efficiency of the boiler exceed 88%.
4. Wide applicability of fuel. According to the different needs of users, it can be applied to a variety of fuels such as biomass pellets, wood chips, palm shells, straws, etc., and is suitable for customers in different countries.
5. During the commerical hot water boiler design process, the furnace arch, the furnace wall and the heating surface of the furnace are arranged reasonably. At the same time, independent wind chambers are designed to ensure the combustion efficiency of different fuels to the utmost extent.
6. The economizer and dust collector are installed at the tail of the hot water boiler, and the primary and secondary winds are reasonably designed to minimize the NOx emissions.
7. The commerical hot water boiler is equipped with a high temperature resistant grate to ensure sufficient fuel combustion and effectively reduce fuel costs.
8. The company optimized the length and width of the grate and the speed of the reducer according to different fuel characteristics.
