Inner Mongolia Autonomous Region for the winter heating long-term, large coal consumption of the actual situation, "strictly control coal pollution" as a top priority to improve air quality.
According to statistics, in 2018, Inner Mongolia fully complete the remaining 10 127 tons of steam / hour and small coal-fired boilers out of the task-level urban built-up areas; Hohhot, Baotou, Wuhai more polluting coal and other built-up urban area start 35 steam tons / hour and the phase-out of coal-fired boilers.
Inner Mongolia this year also completed shantytowns 142,000, an increase of central heating an area of 11.36 million square meters, the "coal to gas," "coal to electricity" pilot project, the region cut loose coal burning 636,300 tons.
In addition, in order to fight the "Battle of the sky" tough fight, Inner Mongolia this year has introduced the "Atmospheric Pollution Prevention Act," "Blue Sky Battle win three-year action plan to implement the program" and other local laws and regulations.
From January 2018 to November, Inner Mongolia Autonomous Region average PM2.5 concentration of 30 micrograms / cubic meter, down 6.3%, the ratio of the number of good days to reach 83%.
When using a chemical plant boilers have what precautions when using chemical plant boiler what precautions? The main industrial production of industrial boiler to provide heat to maintain the power production plant operations, mainly using a fired fire tube steam boiler of electricity or natural gas industry, the other is based on coal as a raw material by the waste heat recovery operation to maintain the production of traditional electric power industrial boilers, widely used in industrial production. What precautions when using chemical plant boiler? (1) When using industrial boilers, the operator should not only have relevant operational knowledge and skills, but also prohibits unauthorized departure, the boiler is no state in the operation to reduce accidents. Pressure boiler boiler water level is too high or too large. (2) staff to improve the working pressure of industrial boilers, should undergo a rigorous technical evaluation of relevant professional departments, before adjustments. Pressure gauge and safety valve to avoid failure resulting industrial boiler overpressure mislead the operator allowed to adjust. Meanwhile, to strengthen skills related to operating personnel, the timely processing of boiler operation anomalies. (3) prior to use industrial boilers, the boiler should be fully checked structure and current and voltage is within the normal range. To avoid unreasonable boiler structure, poor weld quality, safety accessories related failures caused by industrial accidents occurred in the boiler during operation, and should be sufficient for boiler water treatment prior to use to reduce the incidence of accidents in the run and run.
Advanced equipment and principles of fired fire tube steam boiler desulfurization and dedusting analysis of small and medium boiler outlet dust concentration in the combustion of various structures are much higher than the maximum allowable dust concentration values specified in our standard, so in addition to the correct choice burning structure and improve operational level, to burn coal dust boiler equipment must also be provided at the rear of the boiler, the flue dust is then trapped into the atmosphere. Dust into five categories according to their action principle (1) comprises a gravity dust precipitator mechanical force, an inertia dust collector, a centrifugal dust collector. (2) comprises a water bath washed filter dust collector, a foam-type dust collector, venturi dust, water, dust and the like membrane. (3) comprises a filtering dust collector (4) an electrostatic precipitator and baghouse dust particle layer and the like. (5) a magnetic filter. Gravity settling dust collector 1. The principle is: When the flow rate of the flue gas into a large space to reduce soot particles by means of its own gravity larger, natural settling by gravity separated from the flue gas. 2. The cyclone dust cyclone called centrifugation, the principle is strongly flue dust along the cylindrical wall is rotated within the gas cyclone, and gradually decreased along the tubular wall a helical motion. Strong centrifugal force generated by rotation, the cylindrical wall surface of the body thrown dust, dust on the wall surface by gravity to the bottom of precipitator gradually decreased, and is discharged through hoppers. Purified flue gas is discharged from the middle of the dust core tube. Centrifugal mill precipitator 3. The principle is: the tangential direction into the flue gas at a high speed from the lower portion of the cylindrical housing, along the rotating cylindrical wall, the nozzle along the upper circumference of the cylindrical housing into a uniform tangential spray in when the inner wall of the cartridge housing forming a water film, since the centrifugal force, is thrown dust cylindrical wall, and the stick water film and water film flows along the conical hopper, is discharged from the ash discharge outlet, the purified flue gas from the housing an upper discharge.
How much gas 6 tons per hour of fired fire tube steam boilers need? How much natural gas steam boiler needs an hour? 6 tons calorific gas steam boiler 360 million cards, the design pressure of 1.25MPa, the maximum steam temperature 194 degrees, consumption of natural gas per hour at full load boiler 420m3. The above data is only theoretical gas consumption, the actual gas consumption is influenced by many factors. 1, the thermal efficiency of the design; 2, insulation effect; 3, discharge times; 4, fireman professional level; gas and steam boilers are mainstream industrial production equipment. Especially since the implementation of the national coal gas policy, China has not yet biomass boilers and coal-fired boilers appear. Users select the gas-fired most important criteria are reasonably priced, low operating cost, easy to say and difficult choices. What price is only worth buying for key boiler, gas boiler selection is a measure of its quality, how to identify the quality of the boiler? 1, should be sufficient energy, emissions, low emissions; 2, low air consumption; 3, low operating costs; 4, stable; 5, long life; condensing gas boiler advanced design, for flue gas flow reasonable the design optimization. Sufficient heat transfer through the flue gas and smoke tubes economizer, heat the fuel sufficiently. Gas boiler for maximum energy efficiency.
