Gas Fired Steam Boilers are not covered by the rule:

Gas fired boilers (a boiler that primarily burns gas is still considered a gas-fired boiler even if it also burns oil or other liquid fuel during periods of gas curtailment, gas supply interruption, startups, or for periodic testing not to exceed 48 hours during any calendar year)

Recently, Shanxi Province issued a notice "Shanxi win the Battle of Blue Sky 2019 action plan" for the atmospheric environment management direction, the total annual target put forward concrete implementation of the program, as follows.

1, to promote the boiler depth treatment. October 1, 2019, with the province and more than 65 tons of steam coal-fired boilers and located in built-up areas of cities and counties in coal-fired heating boilers, biomass boilers to complete a full ultra-low emissions transformation. Actively promote the orderly transformation of gas boiler low NOx combustion. 2019, the province completed 232 sets of 19060 tons of steam boiler low nitrogen gas Combustion Technology, 40 407 tons of steam boilers ultra-low emission biomass transformation, 907 sets of 4160 tons of steam boiler low NOx combustion gas transformation.

2, continue to carry out special treatment industrial furnaces. The inclusion of 2018 --2019 autumn and winter ban out of the scope of the comprehensive management of air pollution crucial action of industrial furnaces (coal-fired stove in key areas and non-ferrous industry, coal-fired kilns, coal-fired reverberatory furnace, coal-fired lead melting pot and lead electric boiler, coal-fired heating in the cogeneration heating pipe network coverage, kiln drying, etc.) to conduct a comprehensive clean-up, to ensure the elimination ban in place. Expected annual industrial furnaces out of 147 units, industrial furnace-depth treatment of 629 units.

3, vigorously promote clean winter heating. Full use of the complete transformation of the ultra-low emission cogeneration units and large central heating boiler, cogeneration and district heating based, coal to electricity, coal gas and other clean energy sources, supplemented priority to the township as a unit, take piece together the transformation of the way, instead of living and bulk coal for heating.

4, strengthen management and control bulk coal, municipal or county government to promptly clean heating has been completed the transformation of the area designated as a "ban on coal zone" prohibiting bulk coal entering, to prevent the resurgence of loose coal; energy management department should be organized to make clean coal supply protection; market supervision and management departments to increase coal quality sampling, civil bulk coal company coal sales monthly sampling coverage to more than 10%, the annual sampling coverage to 100%.

5, the implementation of total coal consumption control. Optimize the use of coal structure, non-power coal in 2019 substantially reduced compared to last year, accounting for the province to improve coal for power generation coal consumption ratio.

7, shutting down out of substandard small coal-fired units. In the case with cogeneration heating conditions, shutting down the integration of 300,000 kilowatts and heating in the range of 15 kilometers radius of more coal-fired heating boilers and coal-fired units is not up to the small thermal power generating units. In 2019 the province out of 300,000 kilowatts or less is not up to five coal-fired units, 1.02 million kilowatts.

Efficiency of the CFB Combustion Process

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties. According to theEPA's "Combined Heat and Power Partnership Biomass fired cogeneration plant CHP Catalog," the scrubbing action of the bed material on the fuel also enhances the combustion process by "stripping away the CO2 and solids residue (char) that normally forms around the fuel particles . . . allowing oxygen to reach the combustible material more readily and increase the rate and efficiency of the combustion process."

The calculated results indicate that the simulation values are consistent with the experimental values. Effect of 8t boiler for sale industrial georgia load on the temperature of furnace, flue gas emission, inlet and outlet flue gas of economizer was discussed based on the model. Boiler load on the increase results in a increase in temperature of furnace, flue gas emission, inlet and outlet flue gas of economizer. The main performance parameters of 65t/h oil shale CFB boiler system were discussed and preliminarily predicted by the model.
