High Quality Vertical small environmental water tube steam boiler

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.

How to control the temperature of the gas boiler

Kotelshchik was required configuration of boiler equipment at run-time staff, they must not only ensure safe operation of the boiler, but also to maintain sustainable and stable operation of the boiler.

Steam boiler in Henan natural circulation pump and clean fast boiler's high quality vertical small environmental water tube steam boiler Xiao Bian told you about in the natural circulation pump and clean natural circulation boiler is the use of the density difference circulation loop rise and fall pipe soda mixture with water in the pipe to establish the working fluid cycle. Having a drum, a radiation heating surface, convection heating surface and a button connected to a steam boiler, a steam separator, and a larger heat storage capacity of water, more reliable water cycle, water separation was also better. But the drum heat capacity, simple wall thickness, temperature, and speed limits start and stop the boiler drum manufacturing, transportation and installation is also more difficult. Natural circulation boiler further includes two types: a steam boiler, and such a boiler is divided into: 1) Simple cycle: on the drum, the downcomer, the lower header tank or drum, and also some of the riser pipe constructed in parallel there are upper header. 2) Complex cycle: different conditions riser group consisting of linked together by common circulation circuit member. Two hot water boiler in the natural cycle further includes the following three: 1) the whole natural circulation: In addition to an outer surface heating radiation, convection heating surface are all working according to the natural circulation, the use of heating surface bundle structure. 2) Natural circulation predominant: radiation heating convection heating surface area for the most natural circulation, convection heating surface portions of the work by directly using serpentine configuration. 3) semi-natural circulation type: radiation heating surface is natural circulation, convection heating surface by all DC operation, serpentine tube means. Natural circulation boiler For ultra high pressure steam boiler or less, more subcritical pressure employed, but the soda density difference decreases, weakening the flow head, high purification of the steam separator and steam requirements, the highest pressure of 17.3 MPa, the capacity to 2350t / h. Oil cleanliness have a significant impact on the life of the hydraulic pump, in addition to the requirements set forth above, the user must also pay special attention to the following points: 1, must be fuel tanks, pipes, hydraulic cylinders and hydraulic before installing, commissioning clean valves, etc., of the oil must be filtered oil vehicle when filling new oil to the tank, to prevent the contamination caused by the dirty barrel of oil. 2, must be prevented during transport, since the disassembly packing conduit pipe caused by contamination, and the tank element. Thus, hydraulic oil tank and other devices as far as possible the overall packaging system, as few as possible detached pipe, tubing and fittings must be disassembled at all sealed with a dust. 3, the new pump one week after use, the need to once all the oil filter, oil and the oil filter and washed, and then according to machine work load situation 3 to 6 months to replace a fluid, a cleaning tank. 4, during use of the system is prohibited due to heat generation and the injection hole or opening the fuel tank cap.

Installation stratified combustion devices. Stratified combustion devices early in order to prove to the chain grate practical technical boiler, the effect is very obvious, in addition to reducing the carbon content of ash, but also effectively reduce the blast, reduce exhaust excess air coefficient, a boiler blast measured amount can be reduced by about 30%.
