Luoyang, Henan Province issued the "Luoyang coal consumption reductions embodiment (2019-2020 years)", the program proposes: To continue to promote alternative coal consumption reduction, the implementation of industry "electricity instead of coal" project.
2016-2018 years, the city of Luoyang excess capacity, coal-fired boiler demolition, energy saving, clean energy alternative through a series of measures to resolve the power industry, pushing the total coal consumption control achieved some success, but the energy mix partial coal, thermal power installed capacity of migraine and thermal power multi siege pattern has not fundamentally changed, there is still emphasis on the industrial structure, high energy-consuming industries continued to increase the proportion of energy consumption, coal consumption is highly concentrated and other issues. Especially since 2018, comprehensive energy consumption of coke, chemical high energy-consuming industries rise significantly, the whole society electricity demand continues to grow, the amount of coal for power generation system tune up utility power plants rise, not fall, some counties (cities, districts) large-scale industrial coal consumption rise, not fall. Therefore, Luoyang City will continue to work to phase out coal-fired boilers to improve the quality of atmospheric environment.
"Plan" put forward the overall goal of coal governance: By 2020, the city's total coal consumption and strive to 2015, down from about 23% control in less than 20.3 million tons. Among them, the total consumption of non-coal power industry control in less than 9.6 million tons, the total coal consumption in coal-fired units ganged public control in less than 10.7 million tons.
"Plan" requirement, the industry needs all kinds of hot water, steam, hot air in the production process, and gradually promote regenerative and direct thermal electric industrial boiler applications. In the metal processing, casting, ceramics, refractories, glass and other industries to promote electric furnaces, industrial kilns and encourage qualified to carry coal to electricity.
Vigorously promote clean heating pilot city construction, 2019, 2020, respectively, the implementation of urban and rural residents electricity instead of coal, 110,000. 2019, 2020, respectively, to complete the electrical heating 500,000 square meters, 800,000 square meters.
In addition, the "plan" also proposed to accelerate the development of clean energy and new energy, the implementation of comprehensive improvement of coal-fired facilities, the city will no longer approve the domain, and the new 35 tons of steam coal-fired boilers, accelerate the elimination of 35 tons of steam / h and coal-fired boiler.
Propose and discuss a number of issues on fuel steam exact definition of 1 boiler or steam horsepower: For the boiler, the following will be the focus of discussion and explain, for fuel steam boiler which, because it is one of the sites boiler products, it is necessary to learning and understanding. That being the case, it will be through the Q & A format, to initiate and conduct specific, thus, increase everyone's familiarity with this A boiler. 1.3 tons of fuel steam boiler, its gas consumption per hour is how much? 3 tons of fuel steam boiler, its gas consumption per hour is 300 cubic meters. So, if it eight hours a day's work, then, that a day of gas consumption is 2,400 cubic meters. Therefore, specific numerical values, the time will depend on the specific work of the boiler, determined by it.
Equipment maintenance method of a condensing gas exact definition of 1 boiler or steam horsepower, pressure maintenance 1. After condensing gas boiler shutdown the furnace all the water exhausted, the scale furnace, slag clean, rejoin qualified demineralized water. 2. Regular small flame, or periodically using water vapor adjacent to the boiler furnace, the furnace so that the water temperature in the summer condensing gas boiler should be maintained at about ambient temperature of + 10 ℃, winter should ensure that water does not freeze the furnace, close all vent valve, drain valve and drain valve, to prevent leakage. 3. Boiler feed water periodically to maintain the internal pressure of the condensing gas boiler 0.05MPa ~ 0.1MPa prevent air from entering the drum. Second, wet maintenance 1. After condensing gas boiler shutdown at the stipulated time exhausted furnace water, scale, slag, ash cleaned. 2. Close all manholes, hand holes, valves, etc., and the boiler is completely isolated. 3. Prepare a basic protection solution passing demineralized water, boiler water was added per ton of sodium hydroxide Na (OH) 8kg ~ 10kg, plus or sodium carbonate (NaC03) 20kg, plus or sodium (Na2P03) 20kg. 4. The formulated with special pump maintenance alkaline solution into the boiler. 5. When all of the resist solution is injected, the valve opened to fill the qualified demineralized water boiler, until the water overflows from the air valve, and then closing the air valve and the supply valve to open a dedicated pump cycle, a uniform mixed solution. 6. Throughout the maintenance should be periodically maintained with Weihuo drying oven outer heating surface, periodically turn the pump cycle, the concentration of the solution was consistent throughout, but also regularly take the solution assay and the replenishment solution, the PH value of the solution was ~ 10 between 12 to ensure that the alkalinity boiler water. 7. frost winter to take appropriate measures. Third, the dry gas condensing boiler maintenance 1. After shutdown, the boiler water exhausted, scale remove soot, slag and furnace heating surface. 2. Close condensing gas boiler water supply, water supply, the valve on the outfall, or blocked by the separator Yan, completely isolated from the other operation of the boiler. 3. Open the manhole, hand hole, the boiler dry naturally, if the boiler wet, with Weihuo the boiler and furnace wall flue drying. 4. The selection of an appropriate amount of desiccant. Common desiccant anhydrous calcium chloride (of CaCl2) and quicklime (CaO2), CaCl2 2kg per cubic meter of volume of water placed quantitative, requires selection of particles of about 15mm; lime 3kg per cubic meter of the volume of water placed quantitative, requires selection of 10mm ~ 30mm lumps. 5. condensing gas boiler drying, the tray containing a desiccant and the release drum furnace in order to absorb moisture, not in direct contact with the desiccant required boiler heating surface. 6. The desiccant should be checked regularly once placed, heating surface for corrosion to see, the desiccant is failed condensing gas boiler month per week, once a month later examination every two weeks.
Gas exact definition of 1 boiler or steam horsepower gas province tips 1, strengthen the insulation performance of the gas boiler furnace end of the house either warm or radiator, if the housing insulation is not good, a lot of interior heat loss to the outside by thermal convection, and the cold outdoor air and indoor influx, gas boiler continuously heating, the amount of natural gas greatly. The double glazing of windows 20% of energy can be saved, if coupled with thick curtains at the windows, and can save 5% to 10% of energy; Pro out in front of the doors and windows closed, and pull all the curtain for housing insulation. 2, the indoor temperature and reasonable control of the gas boiler to control the first energy SCIENCES scientific room temperature, optimal indoor temperature during the day 20 ℃, 15 deg.] C at night to 17 ℃. As the winter wall gas boiler is normally open, so the temperature does not have to set very high, comfortable on the line, the principle is: water temperature (or the return water temperature) when warmer little lower, cold weather, water temperature (return temperature) to be a little high; start differential be a little cold weather starting temperature difference should be smaller when the days warm. 3, no one at home when the economy many workers would think so, not at home driving a gas boiler waste, save money to go home to open, it is not. If the off gas boiler, gas boiler gas after work will be placed grade rapidly heated, this approach is not scientific, because it is equivalent to start from scratch, since the temperature difference between the room temperature and the boiler temperature is set large, the time required gas boiler fire run, it will not only not saving, but will be more waste gas and increase user exposure to cold time, and there is danger of gas boiler or a heat ends are damaged by frost. In normal use, it can be closed down or uninhabited room heating valve, the gas can be saved to some extent. If a long business trip or gas-fired boiler will yet live, or to warm the water in the radiator drained, so that not only can not use gas, not to worry about gas boiler or a heat ends are frozen
