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.

Shangqiu City, Henan Province in 2018 coal-fired wood boiler grate boxs Chaigai capital subsidy policy

Shangqiu City coal-fired boilers Chaigai target

"Shangqiu City People's Government Office on the issuance of Shangqiu City in 2018 air pollution control campaign of the embodiments notice" clearly requires otherwise, the city completed the basis of 10 tons of steam / h boiler and Chaigai on coal-fired, coal-fired boiler demolition and gradually expand clean energy transformation range, guide and encourage medium-sized coal-fired boilers eliminated. Before the end of 2020, basically eliminated 35 tons of steam / h and coal-fired boilers within the scope of the urban planning area.

Shangqiu City coal-fired boiler subsidy

Shangqiu City coal-fired boiler subsidy implemented gradually decline Chaigai way.

The completion of the coal-fired boilers Chaigai before the end of October 2018, giving 60,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boilers Chaigai before the end of October 2019, giving 40,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boilers Chaigai the end of October 2020, the prize money will not give up. At the same time, it prohibited the use has been shut down, eliminated waste coal-fired boilers taking state funds.

Biomass wood boiler grate box will get more popularity in which near biofuel resource. Advances in pellet combustion and control automation have recently positioned wood-pellet-fired biomass boilers as economical alternatives to traditional boilers. Biomass Boilers offer cost effective alternative to those facilities, factories. People can largest use locally sourced renewable energy such as waste wood, bagasses, rice husk, etc, which saving part of money in boiler fuels.

Biomass fired steam wood boiler grate box have two types in ZG, there are DZL series and SZL series biomass fired steam boiler for sale, DZL biomass fired steam boiler: 2-10 ton/hour,SZL series biomass fired steam boiler: 4-25 ton/hour. Biomass fuel: rice husk, wood, straw, distillers grains, peanut shells, palm shells, corn cobs, etc.
