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.

Efficiency of the CFB Combustion Process

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties. According to theEPA's "Combined Heat and Power Partnership Biomass fired cogeneration plant CHP Catalog," the scrubbing action of the bed material on the fuel also enhances the combustion process by "stripping away the CO2 and solids residue (char) that normally forms around the fuel particles . . . allowing oxygen to reach the combustible material more readily and increase the rate and efficiency of the combustion process."

During installation, the technical team fast 4 ton condensing boiler plant according to the specific needs of our environment, our rational arrangement of stacks, pipes, and other auxiliary equipment, let us bring a lot of convenience in the latter part of the course. Fang fast responsible attitude also gives us impressed, sent a technical team for installation, commissioning and training to us, let us rest assured, peace of mind, peace of mind. --customer feedback

In recent years, with the continuous development of 4 ton condensing boiler industry, all kinds of equipment, including gas-fired boiler, have been further developed and applied. We know that the production of every kind of equipment can be widely used. It has its own advantages, so what are the main advantages of the gas-fired boilers we are talking about today? According to the introduction, it can be understood that gas-fired boiler does not need to accumulate coal ash, so it can eliminate the occupied area. When the gas-fired boiler is used for fuel transportation, the other auxiliary machines are less, the power is small, and the running time is short, so the electricity consumption is saved at a very high level. Production of heat transfer oil boiler. The others, because of the gas-fired boiler, Now it will run out of dust and pollution, and natural gas will be used as a clean energy source. In gas-fired boiler operation, there is no pollution, is easy to achieve. Environmental requirements every night. The daily use of gas-fired boilers needs to be maintained. When the boiler is not used, it should be maintained and maintained. This can not only extend the service life, but also reduce the problems in the process of use. First, when the boiler is not in use, all internal heat transfer oil must be discharged, because if there is oil, the quality will change. If a leak occurs, it will affect the surrounding environment and will need to be cleaned after release. Keep boiler interior clean and keep other impurities. Its Check the parts of the gas-fired heating furnace periodically to see if there is any loosening. After maintenance, the boiler can be stored, can be used directly after the next use, there will be no other problems. Editor reminds everyone, gas-fired boiler after a period of time, will occur loss. If the loss is too high, it will affect its use, especially in some transmissions and connections. Some lubricants are added to these parts to reduce loss and make boiler performance more stable.
