The boiler is efficient, reliable and cost effective.

The functions of 6 tph wood biomass steam boiler in wood processing

Wood fired 4 ton china wood pellet fired 5 ton biomass steam boiler is a closed vessel in which water is heated and the steam is applied to industrial production. Wood fired 4 ton steam boiler for sale in ZG Boiler is a biomass fired steam boiler which mainly takes biomass energy as its energy such as wood and wood wastes; agricultural wastes and crops produced for use as bio fuels; bio-derived fuels, including municipal solid waste, refuse-derived fuel, sewage sludge, animal waste and so on and it is applied in many fields, for example steam boiler in paper mill, textile industry, chemical industry, brewery, pharmaceutical industry, hospital, hotel, school and many other places where need steam.

In this method of combustion, coal fuel is burned in a bed of hot inert, or incombustible, particles suspended by an upward flow of combustion air that is injected from the bottom of the combustor to keep the bed in a floating or “fluidized” state. The scrubbing action of the bed material on the coal fuels enhances the combustion process by stripping away the CO2 and solids residue (char) that normally forms around the coal fuels particles. This process allows oxygen to reach the combustible material more readily and increases the rate and efficiency of the combustion process. One advantage of mixing in the fluidized bed is that it allows a more compact design than in conventional water tube boiler designs. Natural gas or oil fuel can also be used as a start-up fuel to preheat the coal fired steam fluidized bed or as an auxiliary fuel when additional heat is required. Beside, the effective mixing of the bed makes fluidized bed boilers well-suited to burn solid refuse, wood waste, waste coals, and other non standard fuels. The fluidized bed combustion process provides a means for efficiently mixing fuel with air for combustion. When coal fuel is introduced to the bed, it is quickly heated above its ignition temperature, ignites, and becomes part of the burning mass. The flow of air and fuel to the dense bed is controlled so that the desired amount of heat is released to the furnace section on a continuous basis.

To better implement the important speech on the 30th anniversary of the General Assembly Special Economic Zone Xi Jinping, General Secretary Xi Jinping and ecological civilization idea of ​​celebrating to do in Hainan Province, fully implement the "CPC Central Committee and State Council guidance on the full support of Hainan, deepening reform and opening," "CCP central State Council on the overall strengthening of environmental protection and resolutely fight pollution prevention campaign of view "and the spirit of the national Assembly ecological and environmental protection, pollution prevention and resolutely fight tough fight, to promote the construction of national ecological civilization pilot area to ensure the quality of the ecological environment of Hainan can only be more well, not worse, now combined with the actual circumstances of this action.

1, by 2020, the proportion of clean energy installed capacity of more than 60%, to promote low-carbon clean energy priority access. Daly implementation of the "cut cut coal oil" to prohibit new coal, phased out of existing coal-fired units. Before the end of 2020, the province basically eliminated 35 tons of steam / hour and coal-fired boilers.

2, all cities and counties to complete the "high-pollution fuel combustion zone ban" before the end of June 2019 delineation and adjustment. In the combustion zone ban, prohibit the sale, burning polluting fuels. Within the province burning petroleum coke is prohibited. Oil coal quality sampling to establish a regular mechanism.

3, to carry out comprehensive improvement of industrial furnaces, phasing out non-compliance of industrial furnaces, industrial furnace to promote the use of electricity, natural gas and other clean energy or central heating.

4, the full implementation of the construction of urban gas engineering, gas propulsion countryside village "gas on behalf of firewood," to build a gas pipeline network covering urban and rural areas. Demand planning and construction of a number of gas-fired generation projects.

5, to promote the transformation of low nitrogen and ultra-low emissions retrofitting existing gas boiler biomass boilers. Low NOx combustion pollution control measures in new clean energy boiler fueled with natural gas should be used.
