hot thermal system boiler
The daily operation of the hot thermal system boiler adjustment (oxygen papers): oxygen is an indicator to monitor the boiler furnace excess air ratio, it changes the furnace combustion conditions are closely related, if the external loads, combustion, cited air supply, air leakage parameters such as the case where the constant amount of oxygen to the furnace to correspond to fuel heat release. Generally, under stable conditions, furnace heat release amount matches with the supply amount of oxygen remains substantially unchanged, the main steam pressure is stabilized at a certain value accordingly. Oxygen is increased, the furnace described exotherm less than blowing amount, then the pressure will drop, it is required to increase the fuel supply amount, to maintain the pressure. Because of the inertia of the drum and the heat storage capacity of the combustion equipment, the main steam pressure change rate is slower than the rate of change of the amount of oxygen, therefore, concerns the amount of oxygen changes can be determined in advance direction of the pressure change, thereby adjusting the pressure of the functions ahead of the effect of regulation, which is the main basis for regulating a pressure stable operation.
China has put into operation the biomass power projects mainly use water-cooled vibrating grate hot thermal system boiler and circulating fluidized bed (CFB) boiler are two types of boilers. This article is part of the CFB boiler manufacturers through the visit of the technical characteristics and the development of domestic CFB boilers burning biomass as a general introduction.
These are the methods of electric heating steam hot thermal system boiler fast boiler to provide you with the handling of soot in the chimney, if you use electric steam boilers, with more than five can control their own boiler equipment need to be cleared up the flue, and select the appropriate method .
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.
