It is reported that Inner Mongolia has issued a "winning Blue Sky Battle three-year action plan to implement the program," out of shutting down 300,000 kilowatts coal-fired units of non-compliance. Vigorously promote the region's coal-fired units (excluding the circulating fluidized bed and "W" Flame Boiler) ultra-low emission transformation, by the end of 2018, Wuhai City and the surrounding areas all in-service thermal power coal-fired units basically completed the transformation; by the end of 2020 before, with the rest of the transformation of the conditions to complete the transformation of coal-fired power plants all. And promote the implementation of the transformation of ultra-low emissions and steel industries.

First, the implementation of dual control energy consumption. And vigorously promote the total energy consumption and intensity "dual control" to promote the reduction of coal consumption through energy saving. Earnestly implement the autonomous region, "" Thirteen five "comprehensive energy conservation program of work for carbon reduction" and "energy saving" Thirteen Five "plan", by the end of 2020, the region's total energy consumption control at around 225 million tons of standard coal, coal accounts the proportion of total energy consumption decreased from 82.9% in 2015 to 79% unit GDP energy consumption fell 14% from 2015. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal, coal power accounted raise the proportion of total coal consumption to around 55%.

Second, the development of clean energy and new energy. By the end of 2020, non-fossil energy consumption reached about 25 million tons. An orderly wind power and photovoltaic power generation projects, optimization of wind energy, solar energy development layout. Increase renewable energy consumptive efforts to solve the basic wind abandoned, abandoned light problem. By the end of 2020, the region consumptive wind power capacity has reached 45 million kilowatts, 15 million kilowatts of photovoltaic power generation reached.

Out-of-furnace water treatment mainly refers to softening treatment and water quality treatment such as alkali reduction and salt removal before feed water enters a steam boiler in order to remove its hardness. At present, ion exchange water treatment method is mainly used. Ion exchange softening method is to replace calcium and magnesium ions which are easy to form scale in water by using ions which do not form scale in some kind of ion exchanger, so that water can be softened. The hardness of feed water of steam boiler can reach the standard by using ion exchange softening method. Ion exchangers are divided into inorganic and organic groups. The core structure of inorganic ion exchanger is dense and can only be exchanged on the surface. The softening effect of inorganic ion exchanger is poor. It is rarely used before.

Oil-fired boiler maintenance method "two" First, the maintenance of the body of the boiler heating surface: oil-fired boiler heating surface of the body without long-term maintenance methods: dry and wet two kinds. Shutdown more than one month should be maintained using a dry method, the following can be wet shutdown heart month regimen. ① dry maintenance method: oil-fired boiler shutdown put a pot of water to the interior completely remove the dirt, rinse. Dried in the furnace with Weihuo (be careful not to use the fire), then 10-30 mm lime block installed sub-plate, placed in the drum, without contacting the metal with lime, quicklime weight to drum 8kg per cubic meter volume is calculated, and then all manholes, hand holes, pipe valve closed, checked every three months, such as powdered lime broken into, i.e. to be replaced should be re-run the boiler fuel and the disc removed quicklime . ② Wet regimen: post-fuel boiler shutdown until the furnace water cooled to below 70 ℃ furnace water exhausted, the internal completely remove the dirt, rinse, all manholes, hand holes, pipe valves closed tight, and with a blind plate and the operation of the oil-fired boiler completely isolated. Then re-injecting the treated water softener to a minimum safe level of fuel boiler, and then the alkaline solution will be injected into the prepared oil-fired boiler, which ingredients are: sodium hydroxide (caustic soda) per ton of boiler water 8-10kg, if the choice of carbonate sodium (soda ash), the boiler water per ton of 20kg, or disodium phosphate, boiler water per ton of 20kg. After all of the alkaline solution is added, and then injected into the soft water boiler, up until the water out from the boiler at the top, close to the valve, so that the boiler noted mixed alkaline solution. The maintenance period Microflame oven regularly, periodically circulating water, the concentration of the alkaline solution throughout the same. Every five tests also take a basic solution, such as alkalinity less than 5-12mmol / 1 solution should be applied. Cold climates maintenance of law can not be wet, so as not to damage the boiler furnace water was frozen. Second, maintenance of burners: 1, regular cleaning oil filter. 2, to maintain a sense of photoelectric eyes clean. 3, should be at periodic intervals drainage discharge water accumulated in the bottom of the tank and dirt. 4, at regular intervals, cleaning the interior of the burner. 5, the temperature of the vicinity of the burner is not too high, otherwise it will affect the normal operation or damage the combustor components, in particular damage to the control box. 6, near the burner should be kept clean, can not be placed inflammable debris. 7, some components of the voltage instability will cause damage to the burner. 8, to avoid the burners are splashed water.

There is very little pollutant emissions, and national emission standards can be achieved without denitrification equipment. The excess air coefficient of the exhaust gas of the 75-ton power station boiler is only 1.28, and the initial NOx emission concentration is only 139.01mg/m³, which is far lower than the national non-key area limit, and is lower than that of the EU, Japan and other countries. standard.
