zero discharge biomass boiler

How much gas 6 tons per hour of steam zero discharge biomass boilers need? How much natural gas steam boiler needs an hour? 6 tons calorific gas steam boiler 360 million cards, the design pressure of 1.25MPa, the maximum steam temperature 194 degrees, consumption of natural gas per hour at full load boiler 420m3. The above data is only theoretical gas consumption, the actual gas consumption is influenced by many factors. 1, the thermal efficiency of the design; 2, insulation effect; 3, discharge times; 4, fireman professional level; gas and steam boilers are mainstream industrial production equipment. Especially since the implementation of the national coal gas policy, China has not yet biomass boilers and coal-fired boilers appear. Users select the gas-fired most important criteria are reasonably priced, low operating cost, easy to say and difficult choices. What price is only worth buying for key boiler, gas boiler selection is a measure of its quality, how to identify the quality of the boiler? 1, should be sufficient energy, emissions, low emissions; 2, low air consumption; 3, low operating costs; 4, stable; 5, long life; condensing gas boiler advanced design, for flue gas flow reasonable the design optimization. Sufficient heat transfer through the flue gas and smoke tubes economizer, heat the fuel sufficiently. Gas boiler for maximum energy efficiency.

Meanwhile, the transformation of the cost of coal-fired zero discharge biomass boilers, specifically how much, is based on the actual situation of the boiler to set, refer to the following main points.

1, determine the status of the boiler: To understand the current situation in the use of coal-fired boilers, there is almost a new, how about the extent of damage, if there is severe wear.

2, the transformation method: There are many ways of coal-fired boiler, the coal to gas, biomass, coal, coal to methanol to change the status quo are more and more. How you want to change, only partial or total transformation of the transformation, these costs are different.

3, difficult transformation: some boiler design of structural change is better, but some difficult to change the degree of difficulty of the transformation is the technical difficulty of the transformation will affect the final cost.

4, boiler life: life is generally coal-fired boilers in 10 years --20 years, if the stove has been used for more than six years, the extent of the damage is more severe, corresponding to the degree of difficulty and the transformation will also increase the .

In order to improve ambient air quality in the region, Linfen City, Shanxi Province with the actual situation, issued a notice "Linfen City in 2019 iron and steel, coking industry depth reduction plan". "Program" is mentioned, requiring all enterprises in the implementation of the transformation process of governance, compliance with the target, select advanced, mature, stable, and reliable control technology implementation of the transformation.

Trends of biomass CFB zero discharge biomass boiler

Biomass CFB boiler current trends from low parameter gradually to the high parameters of development, from the initial medium temperature and pressure parameters to a medium temperature high-pressure, to high temperature and pressure parameters, even Wuhan Kaidi Electric Power's biomass power plant began to use with independent intellectual high pressure high temperature property CFB combustion technology. The purpose of the development of high parameters to improve the thermal efficiency of the boiler.
