separate firing curves vacuum hot water boilers

How to separate firing curves vacuum hot water boilers, comparative advantages and disadvantages: a vacuum hot water boiler works as follows: When vacuum hot water boiler, the furnace body heat medium water absorption under a negative pressure state of the fuel combustion energy released as heat of vaporization and boiling negative pressure steam of the same temperature medium water, steam and stainless steel heat exchanger for heat exchange, releasing latent heat of vaporization, the water circulating inside the heat exchanger. After the formation of condensed water vapor droplets fall to the heat medium is again heated water evaporated, thus completing the cycle.

It is understood that around prevention and control of air pollution, ecological Environmental Protection Office of Shaanxi Province has formulated the "Boiler Air Pollutants Emission Standards" ( "Standards"), amended the "off key industries in the region of atmospheric pollutant emission limits." In the future, biomass, alcohol fuel boiler emissions also be included in "Standards".

"Standard" is to integrate and improve the local air emissions standards boilers. "Standard" for the scope of the province, covering coal, gas, oil, various types of fuel such as biomass; using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.), gas-fired boiler with reference to the implementation of emission limits.

After calculation, coal-fired thermal power boilers in Shaanxi Province implementation of the new standards, particulate matter, sulfur dioxide, nitrogen oxide emissions respectively about 0.67 tons 15,200 tons, 1.26 tons, down 27%, 40%, 21%; Burning after transformation of coal boiler, particulate matter, sulfur dioxide, nitrogen oxide emissions can be about 01,400 tons, 1.42 tons 14,100 tons.

With the haze pollution reduction work to promote strong, Shaanxi Province coal-fired generating units and 20 steam tons / hour or more coal-fired boiler to carry out the transformation of ultra-low emissions, will gradually iron and steel, cement and other industries to carry over non-electric low-emission transformation, the original standard has been overtaken by change of environmental situation. Additionally, the Guanzhong area of ​​glass, ceramics, bricks, gold and other industry, there are a certain number of kiln, its environmental requirements leniency.

The revision of the "off key industries in the region air pollutant emission standards", the abolition of the thermal power industry, coal-fired boiler emission limit requirements, these two sectors rose to individual standards province-wide.

It also increases the coke nitrogen oxide emission limits Chemical Industries, gold industry, glass and glass products, ceramic industry emission limits, increasing the concentration of tile industries and atmospheric pollutants conversion approach.

The new standards are expected coke chemical industry NOx emissions will decrease 70%, the sintering process the steel industry, the particulate matter, SO2, NOx emissions decreased by 50%, 72% and 67%, respectively.

Hot water boiler tank size is defined determinants and small boilers: hot water boiler, which is a boiler, and, for common and common species, therefore, be familiar with and understand it, is necessary, because in practical work may encounter and use this kind of boiler, therefore, we will have the need to know. And here are some specific issues to expand through this work. In this way, we are also capable of deriving some expertise, rather than nothing. 1. The hot water boiler tank, its size is determined by what? Hot water boiler tank, which should refer to the boiler tank with the water pipe network, rather than directly to the boiler water tank is mainly used to store oxygen or demineralized water. The tank capacity is determined by the size of the fill water of the hot water boiler. In the design of the boiler, is generally calculated according to the cycle of water 3% -5% of the fill water boiler system. 2. The need to gauge pressure hot water boiler in? In addition, vacuum gas boiler, hot water boiler which is it? Pressure hot water boiler, which is a hot water boiler, which boiler the host, there is communication with the atmosphere of the conduit, so that the boiler remains at normal pressure. So, this kind of boiler, does not require installation of a pressure gauge. And vacuum gas boiler which are generally hot water boiler.
