With the steady development of China's economy, the slogans of green and energy-saving have become louder and louder. The introduction and development of gas-fired condensing boilers are obvious to all. The application of this technology not only responds to the purpose of energy conservation of recycling, There are also great benefits to people's lives, so what indicators should high-performance gas-fired condensing boilers include?
1, a good control system is equivalent to the brain, a good brain is the stable operation of a gas-fired condensing boiler, the effective guarantee of safe combustion, the main control objects include burners, circulation pumps, supplemental pumps, etc. A good control system will realize the functions of hand / automatic control switching, working condition monitoring, history data recording, fault self-test and so on.
2, stable output power is the power guarantee for the efficient operation of gas-fired condensing boiler, but the output power is not the bigger the better, but is determined according to the user's own needs, such as the output power of the gas wall-mounted boiler for domestic use. According to the heating area of the room, the area, the indoor temperature requirement, the construction technology of the exterior and interior insulation, and so on, the general consideration can be given to the factors such as the heating area of the room.
3. Safety protection gas condensing boiler belongs to large equipment. If the safety function is not perfect enough, it will lead to internal leakage of burners, inadequate combustion, dry burning and other safety hidden dangers. A good security protection system should meet the following requirements:
1) Boiler temperature display, temperature control, overtemperature alarm and other systems are set independently: 2) Burner fault self-check and flameout protection; 3) Air pressure protection: 4) Gas pressure protection, etc.
4, brand service manufacturers to create a hot-selling gas-fired condensing boiler brand, not only reap huge economic benefits, but also for buyers to use the inspection-free label. The main parts and components of boiler (mainly including controller, pump, expansion tank, etc.) best choose well-known brand products, although the price is relatively high, but can ensure the quality and performance of gas-fired condensing boiler.
Gas hot water central boiler price explosion and treatment methods: Gas explosion is one of the hot water boiler accident more serious accident, have equipment, heating systems and buildings severely destructive and can cause great casualties on social and economic development are causing adverse effects. Gas hot water boiler on the causes of the explosion, fast Boiler summarize the following aspects, and propose effective treatment methods.
The molecular weight of CaCO3 is 100 and the molecular weight of MgCO _ 3 is 84. Therefore, in the case of complete scaling, the theoretical amount of scaling is: CaCO3 scale is 100 × 86.73mol=8673g=8.673kg. MgCO3 scale is 84 × 1.77mol=148.68g=0.149kg. Although the water quality of the central boiler price fully meets the requirements of the boiler supervision regulations, there is still residual hardness in the softened water after reaching the standard. In the operation of the boiler, the water supplied to the system is continuously circulating. The residual hardness will eventually scale at the high temperature of the boiler. The calculated results show that the amount of scaling can reach 8.8 kg in this heating cycle, which has become a threat to the local high temperature furnace tubes.
The Fangkuai Group's unique full-operating central boiler price operation laboratory has an annual operating cost of more than 5 million yuan, which can simulate the operating conditions of various types of boilers under multi-operating environment conditions. The laboratory provides technical tests such as test and inspection, analysis and evaluation, data evaluation, energy saving and environmental protection, and special software from materials to complete equipment, hardware to software, and even complex large systems.
