boiler burner manufacturers for webster
2, the heat value of 8600 kcal / Nm3;
3, the thermal efficiency of the gas boiler is about 95% (Henan fast boiler can reach 98%);
10th June this year, the provincial government agrees that the ecological environment in Zhejiang Province Office issued the "Notice on the implementation of special emission limits national emission standards of air pollutants" (hereinafter referred to as "notice"), marking the full implementation of Zhejiang Province especially national emission limits of air pollutants.
"Special emission limits" is mainly for land development density is already high, the environment carrying capacity began to weaken, or less atmospheric environmental capacity, ecological environment is fragile, more stringent prone to serious air pollution problems in sensitive areas and set the emission limits. Implementation of the national emission standards for special emission limits, Zhejiang Province in favor of further strict pollution management, reduce pollutant emissions, to further improve air quality, but also help promote the integration of the Yangtze River Delta environmental standards.
In fact, back in 2013, Zhejiang has already begun in some areas particularly the implementation of the national emission standards limit emissions of air pollutants, but was limited to Hangzhou, Ningbo, Huzhou, Jiaxing and Shaoxing, Hangzhou Bay five cities; and this is to expand to the province level. In addition to a wider geographical range, "advertisement" clearer pollutant emissions targets, e.g., volatile organic contaminants not individual indicators, including not only non-methane hydrocarbons, total volatile organic compounds such as benzene, benzene and other pollutants indicators meet the definition of volatile organic compounds should be performed; also more involved in the industry, such as boilers only provides original coal-fired boiler, and "notice" it covers all types of boilers (including oil, gas).
It is reported that, in the national emission standards have been implemented, a total of 25 standards set emission limits of air pollutants in particular; at the same time, the recent ecological Ministry of Environment and the State Administration of market regulation has released three national emission standards of air pollutants, namely, pharmaceuticals, paints, inks and adhesives and volatile organic compounds fugitive emission control standards, and will be from July 1, 2019 implementation. According to "notice" requirement, the province is also involved in the enterprise should implement special emission limits specified in the three standards, the execution time of the emission standards time synchronization. Provincial Department of Atmospheric environment Department official said: "The implementation of the national emission standards for emission limits in particular, help to further strict management of our province pollution, reduce pollutant emissions, to further improve air quality, but also help promote environmental protection in Yangtze River Delta standard integration. "
Condensate recovery system can be divided into open and closed recovery system recovery system.
Recovery system is open to a condensate recovery tank to the boiler, the condensed water recovery and utilization in the process, one end of the recovery pipe is open to the atmosphere, i.e., the condensed water collection tank is open to the atmosphere. When the lower pressure of the condensed water, can not be reached by the pressure from recycling properties, high temperature condensed water pump pressure-feeding. The advantage of this system is that the device is simple, easy to operate, a small initial investment; however, a large area of the system, resulting in low economic efficiency, larger environmental pollution, and since the condensed water is directly in contact with the atmosphere, dissolved oxygen concentration in the condensed water improved, easy to produce equipment corrosion. This system is suitable for small vapor supply systems, a small amount of condensate, small amounts of secondary steam system. When using this system should minimize emissions of secondary steam.
In the province's foundation 10 steam tons / hour and the coal-fired boiler burner manufacturers for webster Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, the basic elimination of provincial cities planning area 35 steam tons / hour and coal-fired boilers. Financial awards complement the implementation way of decreasing year by year, to complete the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement; before the end of October 2019 for the completion of the coal-fired boilers Chaigai give not less than 40,000 yuan / tons of steam financial awards complement; before the end of October 2020 for the completion of coal-fired boilers Chaigai no longer give financial awards complement.
