Steam Boilers Electrical Eaab 4

Gas Fired Hot Water Boiler H6

Recently, Tianjin issued a notice to expand the scope of the ban on high-pollution fuel combustion zone, which is based on high-pollution fuel combustion zone ban on the delineation of Tianjin in 2015, to further expand this range, Tianjin has completed the bulk of urban and rural coal clean energy alternative areas have been completed and no did not go to the construction of Wuqing classified as high-pollution fuel combustion zone ban, and to delineate new range of units street town combustion zone ban.

1, the implementation of zoning classification control. Still requires strict control within the range 2015 designated combustion zone ban, prohibited the use of a single steam of less than 35 t / h of coal-fired boiler, steam 35 tons / hr or higher requires a particularly coal-fired boiler for emission limits or ultra-low emission requirements, while a total ban on all kinds of loose coal burning.

2, ban on burning area has expanded. New ban on burning area of ​​3107.99 square kilometers, Binhai New Area and design Dongli, Xiqing, Jinnan, Beichen, Wuqing, Baodi, Ninghe 9 district and Haihe Education Park. After the adjustment, the city's high-pollution fuel combustion zone ban area of ​​830.54 square kilometers by 2015 increased to 3938.53 square kilometers, accounting for 33.05 percent of the city's total area.

3, clearly biomass fuel control requirements. According to local emission standards biomass fired boiler air pollutants Tianjin promulgated in 2018, re-notice provisions of the central city, Binhai New Area, the seat of government of other towns and other key areas of government regulations prohibit burning biomass briquettes .

Boiler equipment has been replaced many times, at present, the main energy of steam boilers electrical eaab 4 equipment comes from gas, it is not only very convenient to use, but also the efficiency of boiling water has been improved effectively. Today's boilers have been used in many industries, for people to bring efficiency at the same time also brought development.

On the protection of Henan gas steam boilers electrical eaab 4 - safety valve (B) 1. Henan gas boiler safety valve must have the following means: ⑴ spring safety valve must lift handle means and preventing movement of the adjustment screw is screwed lightly. ⑵ lever-type safety valve should prevent movement of the self-apparatus and the weight beyond the limitation of the lever guide frame. Means ⑶ weight plate from flying off the safety valve should prevent static weight. 2. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. Several valves as mounted on a short tube directly connected with the drum, the passage sectional area of ​​the short tube is not less than 1.25 times the amount of all the area of ​​the exhaust valve. 3. Valve should normally be installed exhaust pipe, exhaust pipe should be as straight outside, and there is sufficient cross-sectional area to ensure smooth exhaust. Exhaust valve to the bottom of the tube should be fitted with a safe place of drainage pipe. On the exhaust pipe and drainage pipe not allow the installation of the valve. 4. Henan gas boiler valve seat throat diameter of not less than 25mm. Bleed tube valve should be installed in the drain pipe does not allow the valve means. Discharge pipe should be through a safe place, and there is sufficient cross-sectional area and freezing measures to ensure the smooth flow of exhaust. 5. Henan and safety valve for the gas boiler maintenance after a new installation, should check the safety valve open start pressure, pressure from the seat and the back seat pressure. Safety valve reseating pressure is usually the beginning of the start pressure 4 to 7%, the maximum does not exceed 10%. When the pressure is less than the beginning of Kai 0.30MPa, back seat a maximum differential pressure of 0.03MPa. The course of the general safety valve should be checked every year. After checking the safety valve, which began Kai pressure, pressure from the seat, back seat pressure calibration results should be recorded in boiler technology files. After the safety valve by check, should be locked or seal, is strictly prohibited heavy object, move the hammer, the spool stuck any other means to increase the pressure relief valve or safety valve open start failure. Henan gas boiler in operation, the safety valve is strictly prohibited splitting. 6. To prevent adhesions safety valve plug and seat, should regularly do manual or automatic safety valve exhaust, turn on the water test.

Where pressure hot water steam boilers electrical eaab 4 pressure hot water boiler with a different point in?

1, boiler pressure hot water boiler heating system is pressure equipment, with a risk of explosion. Pressure hot water boiler heating system boiler pressure is not always open to atmosphere. The boiler will not explode in any case, good safety performance.

2, pressure hot water boiler to be fitted with pressure gauges, water level gauge and thermometer only pressure hot water boiler, boiler due to the atmosphere, the pressure pot is always atmospheric pressure, there is no risk of explosion, without having to install a pressure gauge.

3, circulating pump pressure hot water boiler heating system is pumping systems engineering backwater sent to the boiler, water pump is generally used. Minutes circulation system to overcome the resistance, but also to maintain the boiler there is a certain pressure to ensure that water does not pan evaporation at high temperatures. Circulating pump pressure hot water boiler heating system is pumping water from the pot, heat pumps are pumps, its role is to overcome the resistance of the system, mainly to overcome the resistance of the valve regulating backwater.

4, pressure hot water boiler can not only supply low-temperature water, but also to supply high-temperature water. Pressure hot water boiler can supply low temperature water <100 ℃ of.
