Dzl Series 4 Ton Boiler


Dzl Series 4 Ton Boiler

Hot water dzl series 4 ton boiler safety valve installation and testing a safety valve should be individually tightness test; 2, set pressure hot water boiler safety valve should meet the following requirements, there must be a safety valve to the boiler in the lower press table pressure setting adjustment; 1.12 times the pressure of the operating pressure setting of the relief valve, the working pressure and not less than 0.07 plus 1.14 times the working pressure and working pressure of not less than 0.13 plus the safety valve should be mounted vertically, and should be installed drain pipe, pipe diameter vent aperture should be consistent with the discharge valve. Discharge pipe should be through a safe place, and should take freezing measures; 4, after the hot water boiler safety valve inspection, should be locked or seals.

What are the requirements for select high and low altitude gas dzl series 4 ton boiler? Physics tells us that the higher the altitude, the lower the pressure, the thinner the air, the oxygen content will be reduced. So, for high altitude plateau, in the choice of gas boilers, what precautions do?

Gas hot water dzl series 4 ton boiler say do what works to find a good brand, there are of course looking for both professional and powerful enterprises, but also a considerable wealth of experience working with clients, so as to ensure the quality of the project.

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 dzl series 4 ton 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.
