1, the safety valve should be mounted vertically in a high position in the pot business, set box.

2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve.

3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly.

4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm.

5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of ​​the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of ​​the passage should not step short tube to 1.25 times the area of ​​all the exhaust valve.

6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust.

7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.

8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve.

With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired 3t oil fired boiler pressure 12 kgs are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas-fired boilers, such as gas-fired boilers, are the most expensive to operate, gas-fired boilers need to be opened with gas pipelines, then, if there is no natural gas pipeline, and hope that the operation cost of the boiler is low, only the choice of fuel-fired boilers. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving.

Gas oil-fired 3t oil fired boiler pressure 12 kg room ventilation system designed along with economic development, energy supply and demand changes in the relationship between environmental protection requirements increase, electricity and oil and natural gas in recent years, increasingly used gas oil-fired boiler. The gas oil-fired boiler room design related to people's life and property security of the country, but also can ensure the normal operation of critical boiler. In addition to the location of the boiler room and capacity to meet the relevant specifications, the design of the ventilation system which is also an important element in the design of the boiler room. However, due to the content of conventional ventilation and manual specification relates to small, there is no specific calculation method is given, designed to bring some difficulties. In this paper, problems in this area, combined with engineering experience of the author, make some analysis, calculation and discussion, put forward their views, for your reference. 1. Design Principles gas fuel boiler room ventilation system

As a leader in the fast side condensing gas 3t oil fired boiler pressure 12 kg, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback
