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.
Henan run several areas, including Henan gas boiler gas boiler operation includes several aspects: daily monitoring and adjustment operations; accident treatment; start and stop; optimal operation mode and technology improvements. When the normal operation of the boiler, the daily operation of the monitoring and adjustment of the operating accounts for the major part. "Stable" is the key, pressure, temperature, water level, negative pressure, milling parameters, etc., remain stable conditions is an important guarantee for safe and economic operation. Briefly, the steady working primarily by "balancing" the means to obtain, for example, outside the furnace combustion conditions and load balance, the pressure is stable; to balance the amount of water and evaporation, is stable water level; primer with the supply air volume the amount of negative pressure equilibrium is stable, according to Henan gas boiler operation adjustment purposes, and in accordance with the purpose of regulating the boiler operation, to take the necessary means of regulation. Daily adjustment of the key - "steam pressure." Among the major parameters of Henan gas boiler, main steam pressure to maintain stability is the key which only the steam pressure is stable, the remaining parameters to stabilize. Unstable steam pressure, steam temperature, the water level will also change, so first of all start from the pressure adjustment. Vapor pressure is divided into an outer and an inner interference disturbance, our plant, i.e. outside the external disturbance load generally little change, so change in vapor pressure are changed within the furnace i.e. interference caused by operating conditions, so holding furnace combustion conditions the stability is the stability of the vapor pressure. If the combustion conditions change, such as wind than powder, coal calorific value and other factors change, a pressure change occurs, requires us to be adjusted, thereby changing into a stable state of the combustion furnace transient state conditions.
What is the state of a burning oil-gas boiler after it is put out? How to judge whether the burning oil and gas boiler is extinguished? Oil-gas boiler manufacturer-gas-fired Fangkuai boiler for you to introduce in detail: The indicator value of the negative pressure gauge in the furnace of oil and gas fired boiler suddenly increases, the furnace blackens, the flame can not be seen from the fire hole, the combustion sound in the furnace disappears, the flame monitor sends out the fire extinguishing signal. Air temperature, air pressure drops sharply, water level drops first and then rises, etc., all of which are extinguished. Due to the auxiliary engine accident caused by the quenching, such as induced fans, blower power interruption, there is also an accident signal; if the fuel supply interruption, the boiler fuel or gas pressure is reduced to zero.
Recently, customers found us, consulted gas boiler safety operating procedures and precautions, in response to your question, our technicians have given the answer. Safety operation rules and matters needing attention for gas-fired boilers. (1) when abnormal phenomenon is found in gas boiler body, how to do control device failure in safety accident should press emergency turn-off button to stop boiler operation; (2) when the boiler feed pump is damaged and the regulating device fails, it is necessary to press the emergency turn-off button to stop the operation of the boiler, (3) when there is a problem with the electric fuel, it is necessary to press the emergency turn-off button; 4 when there is a danger to boiler or personal safety phenomenon, emergency shutdown should be taken; 5. The start-stop of the burner is directed by the boiler controller according to the change of pressure. (this function is automatic) the operator should always observe the change of pressure and stop immediately if there is any abnormal phenomenon. 6. The boiler operator should observe the water level at any time during operation, especially to ensure that the replenishment tank is full of water. Operators should regularly discharge the boiler to ensure boiler water quality. 7. Once an abnormal phenomenon occurs during boiler operation, the operator should shut down immediately and start from the new engine after handling the fault. 8. The incendiary engine operator with three-phase power supply should determine the positive and reverse of the motor before the first start-up, otherwise it will not be able to do so. Normal ignition. (at this time the incendiary machine in ten seconds after the fan stop, control box alarm).
