Recently, the Government Office of Hebei Province issued the "Hebei province coal investment projects coal alternative management approach", mainly to strengthen air pollution control, the implementation of total coal consumption control target. The new "management approach" referred to new construction, renovation, expansion project of coal, coal should carry out the same amount of reduction or substitution (hereinafter referred to as a substitute for coal). Coal substitute coal should be completed before the project goes into operation.

These measures apply to administrative areas in Hebei coal for direct consumption of fixed asset investment projects. It refers to the direct consumption of coal raw coal, washed coal, other coal washing, coal slurry, coal, coal and other raw materials or fuels production and processing or combustion, its coal facilities (facilities, tools) including boilers, furnaces , gasification, blast furnace and so on.

Coal alternative pathway includes the following four aspects: the elimination of backward production capacity, excess capacity and Yajian enterprises closed down, converting reduce coal consumption; the implementation of central heating, reduce coal consumption saving technological transformation or removal of equipment out of coal-fired boilers and other equipment coal consumption; use of renewable energy, natural gas, electricity and other clean energy alternative to coal consumption; the other to meet the requirements of coal consumption reduction approach. Replacement of coal coal project supervision and management, energy conservation authorities responsible for co-ordination at all levels.

（9）Combustion Adjustment method of Oil-fired Gas-fired Boiler

The combustion adjustment of oil-fired gas-fired boiler is successful and the load adjustment can be carried out after turning into normal operation. At this time, the combustion situation in the furnace should be observed frequently. If the atomization of oil and gas is not good, the flame jumps, the flame hits the furnace tank, and the exhaust temperature is too high or too low, the oil pressure, oil temperature, steam volume, air pressure and steam pressure should be adjusted in time to ensure the safe and economical operation of the boiler. The oil pressure and the pressure are related to the boiler load. The adjustment of the oil pressure is realized by adjusting the pressure of the burner or the amount of oil returned. The adjustment of air pressure is achieved through the opening of the valve. When adjusting a load, enter At the same time, the air volume adjustment must be carried out synchronously to ensure the reasonable match between the oil quantity and the air volume, so as to achieve the purpose of economical operation of the boiler.

There are several series of oil and gas steam 70 mw boiler for sales produced by ZG boiler, wns oil and gas steam boilers and szs steam boilers. These two series of boilers mainly use natural gas, petroleum and heavy oil as fuel. The boilers are medium and small capacity boilers, and there is no noise and no ash. The boiler has high automation and convenient operation. The oil and gas boiler is a kind of boiler suitable for the textile industry. A textile factory in Bangladesh has cooperated with Z ZG boiler to purchase two wns oil and gas steam boilers.

A model for the combustion of oil shale in the 65t/h circulating fluidized bed (CFB) 70 mw boiler for sale was developed, consisting of oil shale combustion, steam-water and ash circulation system, calculating the O2 and RO2 content of flue gas emission under three kinds of oil shale combustion in 65t/h CFB boiler.
