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."
Boiler and steam should have what conditions? (1) normal flake type chain grate boiler plant, (2) a suitable material thickness, stable combustion furnace. (3) a pressure slightly lower than the superheated vapor pressure of the main steam pipe, generally 0.05 ~ 0.1MPa. (4) steam temperature between 370 ~ 400OC. (5) Drum Level of about -50mm. (6) steam quality qualified. (7) the tube conduit has fully warmed. Boiler Water Level Indicator How to deal with the failure of the boiler drum water level how to deal with failure? (1) such as boiler drum water level table has a damaged: damage to the door immediately closed water table level, valve, open its doors hydrophobic. With another drum water level meter to monitor the normal water level in the drum. Take urgent measures to repair or replace damaged water gauge. (2) Drum Level two tables are damaged, but the boiler feed water automatically, water gauge differential pressure within one hour and the front drum level table has proofreading, confirmed that the correct and reliable, with reference to the feed water and steam flow meter instructions, continue to run for 20 minutes. In both cases, the squad leader should report the value of long, to maintain the stability of the boiler load, and to take urgent measures to replace the drum level table. (3) If the two tables are damaged drum water level, water level gauge while the differential pressure is unreliable operation, should the emergency shutdown process. How to determine the boiler load plummeted? It plummeted What is the reason? What should I do? Come the following: boiler load plummeted phenomena: (1) steam flow plummeted, steam pressure soaring. (2) found the treatment is not timely boiler safety valve operating will result. (3) decreased instantaneous boiler water level then rises, a high level alarm signal. When the safety valve seat, the water level decreased rapidly, may cause low water level alarm signal. (4) When the transmission switch trip, to swing each of the auxiliary ammeter have abnormally, the flash lighting. Boiler load sharply reasons: (1) an outer line switch trips. (2) steam turbine emergency stop. (3) Isolation Valve core valve or the main valve off. Plummeted boiler load process: (1) The table indicates drum water level, steam and feedwater flow meter, automatic to manual feed water, to adjust the water level. (2) The rise and decline in steam pressure load, and timely Kohiki off, air supply, stop grate, holding BOILERS, open superheater hydrophobic. (3) timely adjustment of desuperheating water gate, so that the steam temperature is normal. (4) If the discovery process is not timely, the pressure exceeds the safety valve operating pressure, and when the security gate does not move, should Stokes Exhaust electric door open, until the normal pressure. (5) make contact with a load preparation, monitor and report the value of long. (6) accident, checked the action over the security door situation, is closed tight. When the boiler drum level is unknown how the "waters"?
Gas heating flake type chain grate boiler operation and management system to resolve the gas heating boiler heating system will be relatively complex, requiring a strict management system to ensure safe heating boiler running smoothly in this process need to pay attention to the following points: 1. The quality of boiler water must to go through rigorous testing, sub-standard water to be softened to avoid scaling, corrosion and other boiler components after use, affecting the thermal efficiency and operational safety late boiler. 2. boiler and its auxiliary system is operating normally, if abnormal timely feedback process. 3. Ensure the indicators boiler water systems, safety accessories and other normal and flexible. 4. boiler operator rigorous specialized training and work and strict management system, be sure to do, patrol officers and operators keep alert, can not be insensitive. Inspection time designated times to be once per hour. Period of time to carry out maintenance and repair timely 5. boiler shutdown. To ensure that the boiler inside and outside the normal indicators, the device remains clean and orderly. 6. In addition, during each inspection of boiler operation, inspection, etc., must do text and data records to ensure that when the transfer of work to be a clear understanding of boiler operating conditions between the transfer of personnel. Of course, the normal norms of these will be far more complex, these are the general direction in which, in any case, to ensure safe operation, the safety of gas heating boiler, while maximizing operating results play a boiler, strict implementation of the operation and management system It is a necessary operation.
