sol bagasse boiler brazil

The users who have used the sol bagasse boiler brazil all know that the hot water boiler will be corroded when it is used for a long time, which has a great influence on the service life of the boiler. So how to reduce the corrosion degree of hot water boiler? I hope the following introduction will help you. 1. The installation of exhaust apparatus in the system of hot water boiler is helpful to eliminate the air in the hot water system of hot water boiler and the gas emitted from water by heating, thus reducing the corrosion of oxygen. 2. Water supply deoxidization: when the rated power of the hot water boiler is greater than 4.2MW, the water shall be deoxygenated; the hot water boiler with the rated power less than 4.2 Oxygen should be deaerated as much as possible. 3, control the PH value of the hot water boiler water: the PH of the hot water boiler water is controlled between 10 and 12, so that a protective film can be formed on the surface of the metal to avoid the occurrence of oxygen corrosion. Corrosion problems threaten the safe operation of hot water boiler and even affect the service life of boiler. It has become an important aspect of boiler management to prevent the corrosion of hot water boiler heating surface and increase the length of boiler service. The above measures can effectively prevent and slow down the problem of oxygen corrosion on the heating surface of hot water boiler, so as to ensure the safe operation of the boiler. .

Emergency shutdown processing steps gas sol bagasse boiler brazil boiler will sometimes burst some cases, faced with the handling of the emergency shutdown. Xiao Bian summary of the situation based on past experience and measures to deal with the emergency shutdown of the boiler, to help you understand more fully the boiler. First, when the following conditions requiring emergency shutdown 1, vapor pressure exceeds the allowed safety pressure, stopping for gas taken, strengthen water supply, after the wind reduction measures, the pressure is still rising. 2, boiler water, water tables have not see the water level in the steam drum water level gauge steam valve closed or measures to increase the water supply, the water level is still invisible. 3, boiler filled with water, the water level has risen to the highest level of visibility, turn on the water but still no visible water level appears. 4, all the water table or pressure gauge all does not work properly. 5, all safety valves, sewage valve does not work properly all. 6, the boiler pressure parts, such as a drum, tube, water wall tubes is damaged, or when the personal security device crisis. 7, water supply equipment failure, nor spare. 8, while the furnace wall cracks during collapse danger. 9, delivery, induced draft fan damaged, can not continue to run down. 10 other events a serious threat to the safe operation of the boiler. Second, the emergency shutdown processing step 1, quickly turn off process. First shutdown burner, and close the gas supply valve to stop gas supply, and then cut off the valve, and finally opening the air exhaust valve or safety valve down precipitation. 2, rapid cooling furnace water treatment. After the shutdown can not continue to feed water to the boiler. When there is no water leakage or water, the cooling time can be shortened, accelerated cooling rate, cooling down the sewage water through alternate methods, and maintain the level. When the boiler is severely short of water, the method can not take rapid cooling, water supply to the furnace is prohibited to continue, otherwise there will be risk of explosion occurred. When the boiler is full of water, should be reduced combustion (fire thought into a small fire), open the drain valve turn on the water, while the opening of the trap on the main and sub-cylinder steam pipe to prevent steam away large amounts of water to produce water-flushing . 3, during shutdown, so that the furnace is not cooled too fast, to prevent the flue gas, the pressure receiving member and other member by inflation port being damaged by quenching.

5, steel flue and reliable insulation measures should be fixed.

6, a fuel gas boiler room boiler should correspond to a chimney, when required by the conditions a boiler flue or chimney common to several units, each boiler should be ventilated suction force balance.

7, when the flue arrangement provided the necessary thermal and environmental measuring point measuring point in place. Single rated evaporation amount is equal to 20t / h or single thermal rating of greater than or equal 14MW oil-fired boiler, a fixed continuous monitoring must be installed in the flue gas dust, SO2 emission concentration instrument.

8, in the flue gas gathering place easily and when many boilers a share or a total chimney flue shall be fitted with explosion-proof door on the flue after each fuel gas-fired boiler, the location of the vent should be conducive to relief, It should be provided without jeopardizing personnel safety and proper position before turning, when explosive gas may endanger the safety of the operator that should be installed on the guide tube explosion relief means.

9, for some long flue boiler room, they should be accounted for resistance, select the appropriate blower, Fan (when there is draft fan), to ensure the smooth flow of exhaust.

10, the chimney should be considered appropriate anti-corrosion measures, chimney flue gas outlet temperature is preferably above the dew point of the flue gas temperature of 15 deg.] C; when the exhaust gas temperature is lower than the dew point temperature of flue gas, the flue gas should take effective measures to prevent the intrusion.

This year, Hubei Province, will continue to carry out prevention and control of air pollution control, effectively promote the province's environmental air quality improved, and issued the "2019 Annual Hubei ecological system of air pollution prevention and control program of work", as follows.

First, ultra-low emissions and actively promote the transformation of key industries. The province's new coal-fired thermal power units fully implemented ultra-low emissions standards. Actively promote small coal-fired thermal power ultra-low emission transformation, Wuhan, Xiangyang, Yichang and other places to complete before the end of 2019. Circulating fluidized bed boiler unit to achieve ultra-low emissions before the year 2019, tobacco dust W flame boiler units, to achieve ultra-low sulfur dioxide emission limit requirements. Ultra-low emissions and actively promote the transformation of the steel industry, the whole process to reduce air pollutant emissions.

Second, the depth of key industries mentioned standard upgrade. Promote the implementation of major cities in key industries especially emission limits, strictly enforce the "Notice on the implementation of some key cities in particular air pollutants emission limits" (Provincial Environmental Protection Bureau Bulletin 2018 No. 2), advance planning to enact governance project, and accelerating coking industry desulfurization and denitrification projects. According to the national unified deployment and actively carry out industrial furnaces governance special action. Complete waste discharge permit issued in accordance with the work list management requirements.

Third, the total coal consumption in key areas to promote control. Actively cooperate with relevant departments to implement controls total coal consumption in key areas, focusing on reduction of non-coal for electricity. With the relevant departments to promote the commercial coal quality control and supervision of bulk coal sales, strengthen the management and control of coal consumption, promoting the use of clean coal.

Fourth, the optimal adjustment of high-pollution fuel combustion zone ban. Control Department of Ecology Environment "high-pollution fuel directory" to improve the demand by the City People's Government in accordance with the ambient air quality, energy consumption structure and affordability, local conditions choose ban combustion zone ban burning of the fuel mix category, supervise the implementation of the relevant control requirements. Urban cities and states to complete high-pollution fuel combustion zone ban optimal adjustment before the end of 2019.

Fifth, to carry out rectification of coal-fired boilers. Carry out coal-fired boilers out of looking back, resolutely combat the resurgence of acts of the boiler has been eliminated. The county level and above urban area actively eliminate 10 tons of steam per hour coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal-fired facilities, in principle, to a new 35 tons of steam per hour of fuel coal boiler. Actively promote the upgrading coal-fired boilers environmental protection facilities renovation and construction of facilities on-line monitoring, adherence to the "gas will change," the principle of steady progress "from coal to gas."
