Fuels that contain a high concentration of ash, sulfur, and nitrogen can be burned efficiently in rice husk fired fluidized bed steam china wood fired boilers while meeting stringent emission limitations. Due to long residence time and high intensity of mass transfer, fuel can be efficiently burned in a fluidized bed combustor at temperatures onsiderably lower than in conventional combustion processes (1,400 to 1,600 °F compared to 2,200 °F for a spreader stoker boiler). Rice husk CFB boiler in ZG Boiler adopts automatically adjusted back feeder of high flow rate and low power. The lower temperatures produce less NOx, a significant benefit with high nitrogen-content wood and rice husk biomass fuels. SO2 emissions from wood waste and rice husk biomass are generally insignificant, but where sulfur contamination of the fuel is an issue, limestone can be added to the fluid bed to achieve a high degree of sulfur capture. Fuels that are typically contaminated with sulfur include construction debris and some paper mill sludges. Good price rice hisk CFB boiler is strictly following the standard of ISO9001 Certification.

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.

SZL series coal fired steam china wood fired boiler, working capacity is from 6 to 30 ton. Our client need a set of 10 ton steam boiler for his paper factory, which is available for biomass fuels like wood pellet, rice husk, etc. According to design, those coal fuels will be sent to boiler chamber by chain grate, transferring coal fuels to thermal power. Although chain grate boiler has lower thermal efficiency than circulating fluided bed boiler, but considering boiler system price and its fuel costs, to 10 ton steam boiler, choosing SZL series chain grate boiler is more economical in total. Besides, our SZL series boiler, has automatic operation system, safe and convenient to boiler operator. Indonesia has rice, cheap and high quality coal resource. Our clients in local prefer coal fired boiler than other boiler with different fuels.

The partnership, fast china wood fired boiler for the user responsible attitude to have left a deep impression on our fireman boiler operation is not very skilled, fast deliberately sent a party of professional and technical personnel for our on-site supervision of installation, commissioning and training to ensure that the latter can operate our good boiler fireman. --customer feedback
