The sudden loss of power running hot water boiler how to do? In peacetime use hot water boilers, power rationing situation is not uncommon in doubt, even though the chances of brownouts occur nowadays additive, but not the spirit of the Skoda probability of occurrence of such cases. Today, web series to teach Skoda, date knowledge of materials such situations arise. First, after the power rationing, Skoda to quickly close the main valve high column of hot water boiler, as it is to avoid the use of internal furnace water heating furnace. Second, the rear spar to close the hot water boiler integrated operational discharge of the main switch with full gas valve. Third, close the column type continuous hot water boiler sewage treatment complete set of valves, and so caused big dating Column appears a series of other hot water boiler lying nest. Fourth, the valve full close to the deaerator oxygen. Fifth, an overview of the top get that done, according to the system produces no problem disabling shutdown control, and check the water flow furnace, gas, etc. There are wooden desirable settings. Column probability of power rationing hot water boiler operation when nowadays can be said to be the basis of very few, but Skoda is still not completely avoid such situations, the provisions of this control standards Skoda understand such situations arise later, just as and so when that happens is not easy to do anything.
Now the boiler on the market, the type of gas-fired boiler using energy-saving technology more and more, condensing technology is one of them. By adding in the rear of the boiler condenser, high temperature flue gas is released through the condenser when a large amount of latent heat supplied to the boiler used again.
Recently, Guizhou Province to combat air pollution, protecting and improving the quality of atmospheric environment, the protection of public health, promote the construction of ecological civilization, and promote comprehensive, coordinated and sustainable economic and social development, in accordance with the provisions of "People's Republic of China Air Pollution Prevention Law" and relevant laws and regulations of atmospheric pollution prevention and control regulations to be amended.
Article XVI: prohibits a planned urban area built or expanded cement, coal chemical, coal-fired thermal power, coking, metallurgy, ceramics and other serious air pollution industrial projects.
Article 24: Prohibition by waste-water treatment, tampering or falsification of monitoring data, in order to avoid on-site inspection for the purpose of the temporary shutdown, open the emergency discharge channel non-emergency situations, abnormal operation of pollution control facilities and other atmospheric discharge atmospheric way to avoid regulation contaminants.
Article 39: It should be the overall planning of urban construction, coal-fired heating in the region, promoting cogeneration and district heating. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired heating boilers have been built coal-fired heating boilers can not discharge standards, should be demolished within the prescribed period the city government.
Shall manufacture, import, sale and use do not meet environmental standards or requirements of the boiler.
41: partial restriction sulfur, high ash coal mining, mining prohibition radioactive and arsenic and other toxic substances than standard coal. New coal mines must simultaneously supporting the construction of coal washing facilities. Have been built coal mines, it should be in accordance with national requirements, supporting the deadline for the completion of the coal washing facilities.
Prohibit the import, sale and burning of coal does not meet quality standards, to encourage high-quality coal burning.
Prohibit the import, sale and burning does not meet the quality standards of petroleum coke.
After ignition, the heating speed of the gas-fired boiler must be controlled at 10 ℃ / hour, mainly because of its high viscosity of oil temperature, low flow rate in the heated surface of the whole equipment and thicker oil film on the wall of the pipe, which is due to the large viscosity of the oil temperature in the cold furnace, and the oil film in the tube wall is thicker than that in the heating surface of the whole equipment. In this way, the heat transfer conditions are poor when used. If the gas-fired boiler heating up too fast in the process of use, it will be very easy to make the local oil film temperature too high. Within a certain temperature range, the equipment is used to remove the remaining water in the system and the trace moisture contained in the heat transfer fluid. The bottom of a gas-fired boiler when the exhaust capacity of its expander is larger than that of the tube at the discharge of the expander. It is necessary to stop heating up and keep constant temperature when the vibrating speed of pipe is accelerated and the swing range of pressure gauge pointer in each part of the equipment is large. Gas-fired boilers can effectively weaken the door of the furnace during operation, so that the length of time in the stage, the amount of water stored in the system and the quality of the heat transfer fluid are different in the course of use, and the short period can be more than ten hours. Gas-fired boilers up to several days long can not be blindly accelerated and desiccated due to the fact that once the water in the system is vaporized violently, the volume of the equipment will expand dramatically, which may not only lead to sudden boiling. Oil The pipes and furnaces in which a large number of gas-fired boilers are ejected from a gas-fired boiler are reduced by the sharp expansion of the position. At this time the circulation pump will not appear its pumping phenomenon, the equipment in the process of operation must not exceed 120 degrees, until the empty tube no longer exhaust steam.
