Recently, Shaanxi Province, to build a good ecological environment, issued a "Blue Sky Battle Shaanxi Province 2019 work program", "clear water Battle of Shaanxi Province 2019 work program", "Shaanxi Province Pure Land Battle 2019 work program", "Shaanxi Castle battle province 2019 work program "and other four major environmental battle to defend the program. Details below.
"Program" is mentioned: this year by optimizing the six policies, tough fight seven games, seven strengthen security measures, the average concentration in urban areas and strive to fine particulate matter (PM2.5) fell 4 percent to ensure that the number of heavy pollution days significantly reduce atmospheric environmental quality improved significantly, people's happiness significantly enhanced blue sky.
3, increase economic policy support to accelerate clean winter heating work, in accordance with the principle of "Jiangyoufalie", the establishment of special funds for air pollution prevention and control arrangements with local ambient air quality to improve performance linkage mechanism.
1, lay the tough restructuring, according to the law closed down quit a number of energy consumption, environmental protection, safety, technology and production of non-compliance or substandard products out of production capacity, before the end of the year, the Guanzhong area basically completed "messy dirty" industrial enterprises and in accordance with regulations cluster comprehensive treatment.
2, tough fight industrial pollution control, focusing on gas-related industrial pollution sources to perform all the installation of flue gas emission standards new online monitoring facilities, the Guanzhong area cement, coke, iron and steel, nonferrous metals, glass, ceramics, tile and other industries, and to ban coal-fired hot air furnace, the coal-fired cogeneration substantially eliminated heating pipe network coverage heating, drying furnace (kiln).
4, clean energy alternatives tough fight, central heating station complete transformation of existing coal-fired clean off the area before the end of the city to clean the heating rate in urban areas off more than 90% before the end of May to complete the Guanzhong area rural village set loose coal governance indeed household inventory; motor vehicle pollution control tough fight, and increase freight railway construction investment, strengthen the construction of urban public transport system, promote high-emission motor vehicle pollution control, Guanzhong area cities and built-up area buses in the proportion of new energy vehicles to achieve 80 %, starting July 1, the province's implementation of six national emissions standards.
"Program" also pointed out that by strengthening the organizational leadership, strengthen environmental law enforcement, special inspectors carry out inspections of air pollution, strengthen grid environment supervision, improve environmental monitoring and control network, strengthen science and technology infrastructure support, strict accountability assessment 7 safeguards to ensure that work effectively.
Of all the heat losses in a chamber furnace, the heat loss from exhaust smoke was the largest, at about 4% and 8%. The main factors affecting the size of Q2 are exhaust volume and exhaust temperature. Exhaust volume is large, exhaust temperature is high, exhaust heat loss is large. In general, Q _ 2 increases by about 1% when the exhaust temperature is increased by 10 ℃ and 15 ℃. Reduce the exhaust temperature, can reduce the heat loss of exhaust smoke. But it is unreasonable and impermissible to lower the exhaust temperature. In order to reduce the exhaust temperature, the heating area at the end of the boiler will be increased, which not only increases the steel consumption, but also increases the flow resistance on the exhaust side, so it is necessary to consume more energy in operation. In addition, the exhaust temperature should be kept higher in order to reduce the low temperature corrosion of the tail heated surface, especially when the fuel with high sulfur content is used. Therefore, reasonable exhaust temperature should be determined by technical and economic comparison. For modern large and medium-sized boilers, the exhaust gas temperature is usually 110 ℃ 160 ℃.
Fuel cost is usually the dominant component, accounting for as much as 90% of the total. It is given by: CF = aF x (HS hW)/1000/ηB Where aF = fuel cost, ($/MMBtu) HS = enthalpy of steam, Btu/lb hW= enthalpy of boiler feedwater, Btu/lb ηB= overall boiler efficiency, fractional.Get a Quote

the cost of generation and the cost of consumption. If the plant has only one steam generator (boiler), uses a single fuel, and has a single steam pressure level, it is relatively easy to assign a cost to the steam. However, in most cases, there are multiple steam sources and multiple fuels. There are also multiple steam pressure levels withGet a Quote
