Heating and hot water daily is an important basis for maintaining the northern region of the normal operation of enterprises; for Legal Daily organs and units, the hot water boiler is one of the indispensable energy equipment. Currently, work is facing north Heating equipment and facilities aging, increase energy conservation and environmental protection requirements and other issues. Daily logistics-related legal person responsible for improving the overall level of heating units, and the response advocated by the national energy saving, plans to purchase energy-efficient heating boiler. Considering the increasingly stringent environmental policy, Legal Daily authorities decided to use natural gas as boiler fuel. Fast boiler for 20 years, specializing in the production brand boiler, which had been successfully assisted more than Beijing enterprises and institutions, to provide clean heating. The party technical consultant fast boiler based on actual usage Legal Daily units, providing commercial condensing units 99KW vertical 1 hot water boiler.

The basic criterion gas boiler operation is safe and stable, how to ensure the safe operation of the boiler, boiler room need to start from the construction and operation of the boiler, specific requirements are as follows: 1, boiler room enough to stay safe passage, and, to be taken outside the boiler door apart manner; 2, the boiler room is provided to the gas leak detection devices, the time monitoring operating conditions of the gas; 3, the boiler room is arranged to meet the fire safety requirements; 4, the boiler operating temperature and pressure can not be too high; 5, gas boiler the water level must not run too high or too low, to be controlled within a predetermined range.

Boiler and pressure vessel safety valve used in Notes (1) Selection of safety valve: safety valve selection must be correct, because each only safety valve can only work within a certain tolerance range of spring pressure, spring preload can be changed the amount of compression, although there is a certain pressure adjustment, but if once more than the specified tolerance range, it can only replace the safety valve. But recently there are some units of the safety valve of the type, size, caliber, and model specifications and other technical knowledge is not very understanding, and therefore did not carefully choose when to install the optional safety valve, operating pressure and spring as well as the final system pressure rating not consistent, easily lead to security risks, so safety valve the right choice is very important. Also note that manufacturing quality safety valve in the choice of safety valve. Some manufacturers in the manufacturing process of a safety valve in the pursuit of profit maximization, thus reducing the manufacturing cost of the safety valve, a portion will eventually lead to poor quality, substandard safety valve into the market impact of end-use. Therefore, we should pay attention to the quality of its manufacturing in the selection of the safety valve. : (2) safety valve Installation: Installation of safety valve occupies a very important position in the implementation of the entire operation, he will determine the affordability of the pressure vessel. Because of the special requirements of its valve structure, on the device or piping valve should be mounted vertically, sideways, or should not use other installation methods. If not installed vertically it is possible because there is no safety valve stem to maintain a vertical position will affect his normal operation, if found that some of the safety valve is not placed in accordance with the design requirements in the process of testing the middle, it would lead to a safety valve not smooth, affect the normal use of the safety valve, and therefore must be promptly corrected. So safety valve installation method is also a need for attention to the problem. (3) safety valve leakage: safety valve in the course of boilers and pressure vessels and pressure pipes, as in there is leakage phenomenon. At a pressure relief valve, no leakage must be processed as soon as possible, otherwise it will lead to impurities and dust impurities scale assembled seat and the sealing surface of the flap. When lifting the valve stem into, if there are impurities are accidentally fall, it is easy to get caught in between the sealing surfaces will eventually cause wear of the sealing surface, leading to increased leakage. While some units at the time of the safety valve leakage, if improper adjustment of safety valve on their own, even with heavy compression relief items, etc., will lead to complete failure of the safety valve. So when the safety valve leakage occurs, should contact professional service personnel as soon as possible the implementation of the dressing. (4) a safety valve set pressure setting pressure relief valve calibration and testing also plays an important role in the operation of the safety valve. To obtain more accurate pressure setting value, we need to strictly control the import safety valve operating pressure medium. When pressure medium is increased to the limit set pressure, it will slow down the boosting speed, when the detector detects proof flap has heard or open, continuous laboratory media heard negative phenomenon, then safety valve inlet pressure obtained at this time, it can be considered a safety valve set pressure. While also a test of sealing performance of the valve. After passing the pressure adjusting valve, it is possible to test the sealing performance of the valve. In parallel with the sealing performance test, you should first adjust the inlet pressure relief valve, in which case the sealing pressure medium source experiments should also be lower than the setting pressure of the same amount of adjustment. Then test the sealing performance of the valve even if it is successful, test the sealing performance of the valve is in line with regulatory requirements. (5) Safety valve tripping problems in the course of the safety valve of boiler and pressure vessel should also pay attention to the problem of tripping. In the process of boiler operation, due to various reasons pulse safety valve action occurs after the main safety valve sometimes will refuse to move appeared situation. If the safety valve relief operation can not be performed effectively, will make the working pressure of the system is carried out at overpressure state, it is prone to deform or equipment damage phenomena, even the explosion of a major security risk. So you want to eliminate the security risks of such an important tool that can be used it is in accordance with the relevant acceptance inspection of the boiler system one by one all the projects, but also well-developed system of automatic protection device, when the safety valve refused to appear when the situation moving, removal media source or energy source intelligence, thus preventing the system pressure continues to climb upward, thereby preventing further expansion of the accident, and even lead to a vicious accident.

How fuel (gas) boiler stack height standards should be implemented as specified? A: GB13271-91 "boiler air pollutant emission standards" in the stack height is not specified for the fuel (gas) boiler. In order to install the units at the time of fuel (gas) boiler to protect the people around undisturbed, you can refer to the boiler emission standards on fuel (gas) boiler stack height is currently being revised in:
