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.

The open recovery system recovers the condensed water into the feed water tank of the electricity atmospheric pressure water tube boiler. During the recovery and utilization of the condensed water, one end of the recovery line is open to the atmosphere, that is, the collection tank of the condensed water is open to the atmosphere. When the pressure of the condensed water is low and the self-pressure cannot reach the reuse site, the condensed water is pumped by the high-temperature water pump. The advantage of this kind of system is that the equipment is simple, the operation is convenient, and the initial investment is small; but the system covers a large area, the obtained economic benefit is poor, the environmental pollution is large, and the dissolved oxygen concentration in the condensed water is directly contacted by the condensed water. Increased, easy to cause equipment corrosion. This system is suitable for small steam supply systems, systems with a small amount of condensed water and a small amount of secondary steam. When using this system, the amount of secondary steam emissions should be minimized.

Precautions have chosen Pinghu fuel steam electricity atmospheric pressure water tube boiler which ones are more users in the selection of fuel steam boilers, because it is difficult experienced skills, always do not know how well the beginning. Many series due to fuel steam boilers, and construction is not the same, not the same producers, many of whom are kind of do not know how to select the next part of the public choose to teach tips. The key, select the appropriate fuel steam boiler, certainly wants to understand fuel steam boiler construction, the equipment should be set up to regulate the use, should also check and maintenance, so be sure to comply with reasonable structure before smoothly. Second, everything will have a certain amount of fuel steam boiler steam pressure, but everyone in the course will have a certain amount of loss, which also should be selected enterprises in the fuel steam boiler series pay more attention to supply and demand confluence good then select. Thirdly, we should pay attention to on the one hand there are more fuel steam boiler with the equipment, those are good complementary effect can best reduce consumption, energy use. Therefore, in the process of selecting fuel steam boilers, the above said it must pay more attention to these matters, so only choose the right products, to facilitate the best use of use.

In the process of using steam hot water electricity atmospheric pressure water tube boiler, when the water containing impurities enters the boiler, with the continuous evaporation and concentration of water, the concentration of impurities in the water increases gradually. When the boiler reaches a certain limit, it will bring some adverse effects to the boiler. The way to deal with this situation is to discharge the boiler, so what matters need to be paid attention to when discharging the boiler? The following is a detailed introduction for everyone. (1) before discharge, the boiler water level shall be adjusted slightly above the normal water level. When discharging water, closely monitor the water level to prevent gas-fired boilers from running short of water as a result of pollution discharge. After sewerage, there can be no more sound of water flowing in the pipe. After a period of time, then touch with your hand. Sewerage pipe, if the feeling temperature is high, indicate sewage valve has seal condition, must find out the reason to be eliminated. (2) according to the principle of diligence, less row, and uniform arrangement, each shift should be discharged at least once. When a gas-fired boiler has several sewage pipes at the same time, all sewage pipes should be discharged in turn. If only one part is discharged and no other part is discharged for a long time, the water quality of the furnace will be reduced or some sewage pipes will be blocked. It can even break the water cycle and have a pipe explosion. When multiple boilers use one main drainage pipe at the same time, it is prohibited to discharge water simultaneously to prevent the sewage from flowing back to the adjacent boiler. (3) Sewerage shall be discharged after the boiler is pressed or at a low load When, at this time boiler water circulation is slow, the slag scale is easy to accumulate, the discharge effect is good. (4) the discharge operation of gas-fired boiler should be short and discontinuous, that is to say, after each discharge valve is opened, it should be closed again. So repeated several times, rely on suction to make the slag quickly confluence to the sewage outlet, and then centralize the discharge. If the first discharge time is too long, the concentration of slag scale in the pot water is first high and then low, which not only reduces the discharge effect, but also increases the amount of sewage discharge, thus causing the local water circulation to fall. (5) the adjustment operation of the surface discharge is realized by the opening of the regulating valve, and the value is determined by the test results of the water quality of the pot. It is possible to discharge steam hot water boiler on a regular basis. In order to make the boiler water quality meet the standard requirements, maintain good water quality, slow down or prevent scale formation, ensure the use of steam hot water boiler.
