To proceed from reality, should be in accordance with the electric power, gas should the gas, the coal should be coal, should be hot the thermal principle, promote the use of all kinds of clean energy for winter heating cleaning. In order to reduce air pollution and protect people's warm winter as a foothold to enterprises, government promotion, residents can withstand the principle of gas after the first change to gas will change in gas assurance, the price is acceptable on the basis of sound promote the "coal to gas" and central heating engineering, in district heating supply pipe network can not cover, vigorously implement the replacement of coal-fired power heating project.
Good job of marketing system storage capacity for natural gas. Accelerate the construction of natural gas transmission and distribution network, the new natural gas volume priority for life and severe winter areas of urban air pollution and coal for heating alternative. In principle, to new natural gas cogeneration and gas chemical projects.
Accelerate agricultural and pastoral areas "coal to electricity," the process of upgrading the power grid. Coordinate development of power transmission project construction, etc. are encouraged to promote the regenerative electric heating. Around on the "coal to electricity" project supporting grid should be given support, coordination "of coal to electricity," "coal to gas" land for construction.
In accordance with national requirements, shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.
According to air quality improvement requirements to accelerate the delineation of high-pollution fuel combustion zone ban and to expand the scope of, and actively promote the elimination of small coal-fired boilers. The county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers and tea furnace, stove and other operating coal-fired facilities, in principle, to 35 tons of steam per hour, the new coal-fired boilers, in principle, other areas on no new 10 tons of steam per hour of coal-fired boilers. While banned out of coal-fired boilers, pressure boilers market regulators cancellation of registration certificate to use.
Prevent gas thermal power plant boiler steam generation flow diagram explosion focus is that all three at the same time not to reach a certain limit. Among them, air is everywhere, to get rid of this condition is very difficult, so the focus is concentrated in the explosion on the gas and heat. So, at this stage almost all of the gas explosion-proof technology has focused on how to deal with gas and heat.
Poor water quality caused by damage to the thermal power plant boiler steam generation flow diagram: poor water quality, means the water contains a lot of impurities. Boiler feed water may contain impurities in the raw water are: suspended solids, colloids, organic matter, inorganic salts, heavy metal ions, and the dissolved gas. If this water without any treatment, once inside the boiler, will bring the following hazards:
How how water gauge steam thermal power plant boiler steam generation flow diagram testing fast boiler company in Henan following Xiao Bian told you about steam boiler water level meter testing. Water table is a steam boiler operation is safe instrument to prove. Here are just by the Henan fast boiler's water table is how small series steam boiler inspection. Steam boiler water level table index is normal, this question is the key to the safe operation of steam boiler to effective decision-making, so that each of the following safety testing method is particularly important. Water table: Each steam boiler water means at least two tables, it can be used normally, water table conveniently placed for observation and illumination, 6m above the water table during operation from ground level installation of the remote display device. At the same time direct reading water gauges must ensure that the normal use of the water table there is a clear sign indicates the highest and lowest security level and normal water level (red bar). A lower water gauge visible edge of at least the minimum safe level of less than 25mm, the upper edge of the visible higher than the highest security level at least 25mm, normal water level in the middle of the table. 1, the water table clearly show the normal water level, wash at least once per shift, to prevent false level 2, level 3 Table no leakage, water tables have drainage valves, and have received a place of safety release pipe 4, water table and the drum soda connecting tube with a valve between the boiler must be run when the valve between the inner diameter of the connection pipe soda fully open position 5, the drum water level gauge is not less than 18mm, the diameter of the inner diameter of the flow channel and valve water gauge glass is not less than 8mm. Minimum security level steam boiler tube should be able to ensure reliable water supply to decline. Therefore, the population decline tube should be at least 300mm away from the drum minimum safe water level; declining population should leave the water wall tube of the riser pipe farther, center distance should be at least two to three times the diameter of the drop tube.
