DZL series biomass boiler design compact structure, single cylinder longitudinal arrangement, natural circulation mode. Biomass fired boiler supply model is complete, water wall tube arranged on both sides of the drum into an airfoil, effectively prevent the bottom of the drum due to scaling and bulging phenomenon. Boiler tube plates are designed to be arched to prevent cracking under welding stress. The fire pipe adopts the threaded smoke pipe to strengthen the heat exchange and improve the thermal efficiency. The flue gas trend is three return routes, so the starting temperature rises quickly. This series of boilers adopt fixed grate combustion mode, small area, convenient installation, reduce investment, and simple operation, convenient maintenance, save time and material, can use a variety of coal. The boiler runs stably and reliably, the steam supply is stable, adapts to the load change ability is strong, the thermal efficiency is high.
Biomass industrial boiler using light small scale chain grate can feed uniform, convenient control and more stable combustion. The design of this type of boiler has been optimized, the problem of easy coking has been solved, the thermal efficiency has been improved significantly, and the fuel cost has been saved. The boiler series is mainly composed of drum, convection tube tube tube, circulating down tube, pyrotechnic tube and flue, grate, combustion chamber, economizer, water level gauge on furnace body, pressure gauge, safety valve, blowdown valve, coal bucket, slag removal device, operation ladder and platform, etc. The above parts are assembled together in the factory, and the metal plate shell and insulation layer are outfitted into the whole equipment, which is called the quick loading boiler.
Biomass energy refers to the use of natural plants and urban and rural organic waste conversion. Energy produced. At present, biomass which can be used as energy mainly includes straw, forest and tree fruit, livestock dung, organic domestic waste and organic waste water. With the shortage of energy, energy conservation, emission reduction and environmental protection, the international community generally began to pay attention to biomass energy, countries have taken effective measures to encourage the development of biomass energy industry, the effective development and utilization of biomass energy has increasingly become the focus of investment and development in the international energy field.
Biomass fired boiler supply is equipped with automatic ash removal device, which can remove the ash on the heating surface of the boiler in time to ensure the stable operation of the boiler. Boiler models of 2-20 tons, also can be customized according to customer requirements. The convection tube bundle of this series of boiler products adopts threaded smoke tube, which makes the flue gas spiral rotation, high heat transfer efficiency, and improve the independent thermal efficiency and gas production. The water capacity of the boiler is large and insensitive to the fluctuation of the load, so it is suitable for users with a wide range of load adjustment.
The front and rear arched tube-plates of DZL series boilers effectively improve the flexibility of tube-plates, thus reducing the thermal stress of the weld at the end of tube-plates and preventing the cracking of tube-plates. The large volume furnace and the wing flue can effectively reduce the local high temperature at the bottom of the drum, prevent bulging, and effectively reduce the concentration of smoke and dust emission and smoke exhaust temperature. Higher front arch and lower back arch, rapid ignition, large combustion area, high ash burning rate, improve boiler thermal efficiency.
Biomass fired boiler supply using flue gas three return design, independent air chamber, complete or assembly type. This series of biomass fired boilers have the advantages of compact structure design, short installation cycle, small occupation area, fast temperature and pressure increase, simple operation, convenient maintenance and high thermal efficiency. The grate side seal structure design of Zozen Boilers is advanced and reasonable, which avoids the defects of side seal stuck grate and uneven air distribution on both sides of grate and burning the side seal. Boilers of 4t/h and below adopt side seal cold Angle steel bars structure, boilers of 6t/h and above adopt contact side seal under seal structure.
