high efficiency wood pellet boiler

2019, Nanjing for more stringent ozone pollution, for volatile organic compounds, governance and control measures nitrogen oxides unabated.

Nanjing Ecological Environment Agency staff members at atmospheric introduction, with the recent temperature increases, there has been a trend in some parts of ozone exceeded. This summer, the environmental protection department will introduce stricter air pollution control measures, starting from the two aspects of governance volatile organic compounds and nitrogen oxides to reduce ozone pollution.

It is understood that Nanjing will be completed this year 44 companies VOCs governance and thermal power, cement, bricks and other building materials industries fugitive emissions-depth treatment in the city in batches with a gas-fired boiler 936 units, the implementation of the nitrogen oxides governance Sector Engineering; city station 475 to achieve ultra-low emission particulate biomass boilers, for the privately polluting fuels blended biomass boilers embodiment eliminated. It is worth mentioning that the revised "Nanjing Atmospheric Pollution Prevention Act," to be implemented next month. Among them, organic solvents, paints use, as well as volatile organic compounds corporate governance and management have put forward new demands.

Biomass fired high efficiency wood pellet boiler designs include coal-fired boilers with chain grate stokers, wood fired boilers with fixed grates, as well as custom-designed waste heat boilers. All biomass fired boilers are designed and manufactured to latest Standard, such as AMSE. In ZG, Biomass fired steam boiler for sale is devided into saturated steam boiler and overheat steam boiler and meet the needs in seperated.This series boiler belong to chain grate boilers, designed for blowdown on surface and the quality of steam is pretty good. Biomass fired oiler main body and grate adopt large parts for ex-factory, short installation time and low charge for installation. biomass fired boiler capacity of 4-35T / H (2.8-29MW).

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.

Biomass fired steam high efficiency wood pellet boiler 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.
