cost of waste heat recovery boiler in moldova

According to statistics, Zhejiang Province, coal consumption totaled 145.91 million tons, accounting for 56.8% of primary energy consumption in the province. Although after careful environmental management, but the main coal-dominated energy consumption remains high in the province's total emissions of air pollutants. In the "Zhejiang Air Pollution Control Action Plan (2013-2017)" issued in December 2013, the coal-fired pollution control remains a top priority.

According to "Zhejiang low-carbon development" Thirteen Five "plan", as of 2020, the province's proportion of non-fossil energy sources will be increased to about 20%, the proportion of the total coal consumption should be reduced to around 42%.

June 15 this year, Hangzhou Iron and Steel Group ironworks blast furnace in the chimney successful blasting, declared the "three noes" no way to urban development of Hangzhou steel companies, no coal-fired generating units, there is no standard yellow car.

To control pollution from coal-fired source, Zhejiang Province, facing elimination from the transformation of the boiler parties policy, funding, pricing, comprehensive resources supporting the work in 2015, 2016, 2017 were given every right out of steam coal-fired boilers tons 15,000 yuan, 12,000 yuan and 10,000 yuan subsidy funds.

To eliminate 10 tons of steam / hour of coal-fired boilers, in October 2014, Zhuji City, party and government "leaders" personally took, within three months, through the introduction of reward and subsidy standards, regular assessment and other measures, the city's 1964 stage production behind coal-fired boiler demolition 1508 units, 390 units to natural gas or electricity, and the rest use biomass fuel, gas tank or centralized heating, completed the task of transformation. It is estimated that, this year more than 500 tons of sulfur dioxide emissions.

After a clear goal, the province's coal-fired boiler (kiln) transformation to accelerate out of the furnace. According to statistics, in the first half of this year, Zhejiang Province eliminate small coal-fired boilers 6200 Taiwan, has completed 77.5% of the annual task of eliminating.

What preparations before a gas steam cost of waste heat recovery boiler in moldova operation needs to check various instruments, meters are normal. B, circulating water system and the boiler feed water system, without exception, each of the valve opening degree reaches a predetermined state. c, check gas pressure not less than 10000Pa, gas pipeline leak. d, reset operation before combustion process controller. E, soft water tank check, confirm adequate water to open the valve. f, check the boiler water supply is normal. g, demineralized water inspection system is working properly. h, check the dosing device is working properly and adequate dosing barrels of liquid. i, if there are other abnormalities within the boiler inspection. j, check the boiler water level, pressure, temperature, ignition and flame detection of the four protection means, the fuel feed line pumps and valves be carefully checked debugging. k, after the above examination was normal, by air through the main power switch to turn the key switch, without passing inspection and testing of the boiler, the ignition operation is prohibited.

But not as long as the use of gas-fired cost of waste heat recovery boiler in moldova can, according to China's introduction of the latest air pollutant emission standards, Beijing and Tianjin, the Yangtze River Delta and other regions, and Zhengzhou, Xi'an and other cities ever to perform the most stringent air pollutant emission standards --30 mg / cubic meter. Many enterprises due to gas-fired boiler installation time relatively early, current nitrogen oxide emissions higher than this standard, however, when the burner exhaust emissions can not meet the standards formulated by the state, need to deal with the transformation of low nitrogen may continue to be put into use .

In natural gas fuel for example, the high heat of about 9500kcal / m³, low heat generation of about 8600kcal / m³, a difference of about 900kcal / m³, 11% of low calorific value, choosing condensing cost of waste heat recovery boiler in moldova compared to the conventional type boiler reduce operating costs of gas around 11%. (High and low calorific details, see) Second, condensing boilers more environmentally friendly. Compared with conventional coal-fired boiler, condensing boilers are generally clean and environmentally friendly natural gas as fuel, the exhaust gas boiler having a much reduced, alleviating urban air emissions of sulfur oxides, nitrogen oxides, dust and other harmful substances, green pioneer in environmental protection boiler products.
