electricity steam boiler

Traps are generally installed in the electricity steam boiler which position? Boiler traps role recently have several customers to inquire trap in which position the boiler, play what role do? The following content is explained and illustrated Hengyu energy equipment technician made against these two issues. Steam case of condensation to form water is condensed into water to remain in the original equipment or system will cause operation steam pipe water hammer or vibration, we run do not want it condenses into water, but the system related equipment into steam when there are a warm-up process, during preheating, the steam temperature above ambient temperature or above system-related equipment in case of condensation will form water, we will promptly take it sparse, this is what we often say hydrophobic role of discharging the water trap is to avoid or reduce the vapor-liquid two-phase, rapid cooling and flushing equipment, causing damage, vibration or the like. Natural circulation oven set came in the early start can enhance water drum, water wall of water cycle, in order to facilitate the analysis can also be attributed to the ranks of water drainage. But generally not so called. Some feed water pump also turn on the water pump warm, this logic I should go water drainage. , The heating system circuit is formed, to ensure continuous heating capacity of the heating system. The heating pipes, air heater, the level of hydrophobic plus the like. The general effect of the trap in order to prevent excessive pressure level variations into the same vessel hydrophobic or hydrophobic anti-channeling cause vibrations, which facilitate a slow, free expansion, such as a collecting box provided different hydrophobic side platoon expansion furnace according to different pressure levels, machine high accident hydrophobic expansion plus side, the body hydrophobic expansion and the like. If the pressure level deviation is too large hydrophobic into the same container, the container is required to have a large enough expansion space, ensure that the pressure after the expansion is still lower than the lowest pressure when the maximum hydrophobic sparse amount of water. Drainage systems connected to put a lot of water pipe (which are mostly consumer-pressure drainage, the main purpose is not to warm the pipe so do not consider the issue of expansion), turn on the water should pay particular attention to these! In practical operation, the discharge should be considered connected to the same pressure level in the water pipe water drainage, avoiding anti-channeling drainage, in particular of a pressure-dissipating system is isolated from the other systems do maintenance measures eliminate pressure isolation to prevent channeling anti-scald soda !

Daily use of gas-fired electricity steam boilers is mainly used in winter heating, maintenance to pay attention to the smooth flow of flue gas and air leakage phenomenon. These tasks are simple, but many families forget to maintain gas-fired boilers or never think about gas-fired boilers. This will seriously affect the service life of gas-fired boilers and even more serious problems.

Heard so much about fast electricity steam boiler made a number of achievements in the areas of clean boiler, this time my unit and quick cooperation parties, give me your company's boiler unit is in line with the requirements of our team boiler, to achieve a clean, energy-saving, environmentally friendly way of heating . Moreover, your company for the Beijing authorities have provided more office cleaning boilers, a good reputation. So, we finally reached a cooperation. --customer feedback

Condensing steam electricity steam boiler thermal efficiency condensing steam boiler analysis is the use of flue gas condensation heat recovery efficiency of latent heat is absorbed in the rear of the boiler flue gas and the sensible heat released by condensation of water vapor, to achieve the purpose of improving the thermal efficiency of the boiler. Boiler system, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated without considering the heat loss of latent heat of vaporization of fuel in the high heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat of condensation and sensible heat in the flue gas water vapor. Flue gas-fired condensing heat recovery steam boiler flue gas volume components typically produce 15% to 19%, the water vapor content of the oil-fired boiler flue gas is 10% to 12%, much higher than in coal-fired boiler water vapor content below 6%. Currently the thermal efficiency of the boiler are low calorific value calculation, although nominally higher thermal efficiency, but because of high natural gas, low calorific value difference of about 10%, the actual energy efficiency to be increased. To take full advantage of energy, reduce exhaust gas temperature, flue gas heat recovery physical, when the wall surface of the heat exchanger flue gas temperature below the dew point temperature, water vapor in the flue gas will be condensed, releases latent heat, low and high 10% calorific value difference can be effectively utilized.
