2. Circulating fluidized bed (CFB)

Circulating fluidized bed combustion(CFBC) Advantages :

1. Fluidized bed can burn a variety of fuels-coal as well other non-conventional fuels like biomass, petro-coke, coal cleaning waste and wood. This bed contains only around 5 percent coal or fuel. The rest of the bed is primarily an inert material such as ash or sand. Fluidized bed boilers are capable of burning a wide range of fuels cleanly, including biomass fuels such as wood waste.

2. The Temperature in FBC is around 800-900°C compared with 1300-1500°C in pulverized coal combustion (PCC). Low Temperature helps minimize the production of NOx (nitrogen oxides). With the addition of a sorbent into the bed (mostly limestone), much of the so2 formed can be captured. The other advantages of FBC are Compactness Ability to burn low calorific values (as low as 1,800 kcal/kg) Production of ash which is less erosive. Moreover, in FBC, oil support is needed for 20-30 percent of the load versus 40-60 percent in PCC. FBC based plants also have lower capital costs compared to PCC based plants. The capital costs could be 8-15 percent lower.

It features gas boiler on wood gas boiler is a very environmentally friendly boiler, it can be widely used in various fields, and very loved by the people. The main fuel is natural gas boiler, does not produce harmful gases when burned, and the compact structure of the boiler, sealing, and natural gas can burn more fully. Also known as gas-fired boiler gas, or natural gas is a combustible liquid fuel. Heat carrier. Forced liquid circulation by the circulation pump. After the delivery of energy to the heating equipment. Roll- type DC special industrial furnace reheated. Widely used The petrochemicals in textile dyeing. plastic, rubber, food processing. wood processing. asphalt heating. carton production. dehydrated vegetables. lacquer. die casting sand drying and the like, can also be used ≤350oC baking, steaming, shaping, the molten ,dry. Gas boiler structure compact boiler heating surface of the body, the inner heating surface, closely spaced outer disc configuration, the inner coil is a radiation heating surface, an outer surface of the outer coil and the inner coil constituting the convection heating surface. A boiler combustion chamber with a lower and upper body, a combination of the construction site. After combustion combustion combustion chamber, most of the heat is absorbed by the radiation heating surface, high temperature flue gas enters the convection heating surface for heat exchanger, after the boiler combustion air required for heating the boiler air preheater, and then through the filter the fumes to the chimney draft fan into the atmosphere. Easy installation, as long as the upper body and the lower combustion chamber can be closed, short installation period. Heating disk surface using the close-packed tubes, sufficient heating surface is arranged to reduce heat load surface of the tube, to make safer. Media reasonable process, low-Tian (imported) to (export), the gas generated by the operation, to better improve the thermal efficiency of the boiler. The fuel in the combustion chamber of the adiabatic combustion, combustion ignition make easier, more complete combustion, improved thermal efficiency and better crossing. Boiler top close-packed arrangement of coils, to better protect the roof, the roof to avoid burnout phenomenon.

20 tph SZL series biomass fired steam boiler on wood for wood industry

Sichuan Energy Investment has always formed a profound cooperation with ZOZEN. As an important window for opening up to the northeast of China and participating in the international specialization, Suifenhe has developed into a large-scale Russian wood import and distribution center. With the rapid development of the wood import and export processing industry, the ZOZEN SZL series biomass steam boiler project was installed here, providing concentrated steam for wood drying of wood processing enterprises in the Sino-Russian trade zone.

Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler on wood. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
