The difference between hot water and steam direct method for boiler efficiencys of the boiler as a heat medium for air conditioning, heaters, low temperature oven drying equipment, textile and the hot water tank is heated by a variety of low-temperature, heat transfer and air-conditioning coil equipment. Hot water as a heat medium has the following advantages: 1. Generally the lower the heat medium water temperature of the heat medium, and large temperature difference between the flue gas, boiler exhaust gas temperature is relatively low, and thus higher boiler efficiency. 2. Closed hot water supply system small amount of water and sewage rate is much smaller than the steam boiler, waste water is also smaller. And lower boiler water quality requirements, less the cost of water treatment. 3. The specific heat capacity of water is large, a large hot water system capacity, strong heat storage capacity. When the thermal conditions or hydraulic failure condition a short time, without significantly heating conditions cause large fluctuations. 4. pump hot water heating system can be used for long-distance transportation, a small heat loss, heating large radius, to adapt to the requirements of urban planning central heating. The hot water temperature is low, less heat transfer coefficient, thermal efficiency is relatively low as the heat medium heating major drawback. Present predominantly of boiler steam boiler, steam as a heat medium main advantages are: a low cost, wide adaptability, can meet the heat requirements of the various users have different requirements for temperature and pressure simultaneously; 2 nontoxic. directly heating food, even if leaking would not harm the environment; 3 high steam temperature, a large latent heat of vaporization, the heat transfer area can be reduced relative to the hot water device, reduce costs; 4 hot inert small, heat faster when the steam supply, the cold disappear just as quickly when the steam stop. Since the heating medium steam condensate recovery is difficult, resulting in waste and water latent heat. Even with condensate recovery, condensate recovery in the process, because water easily dissolved oxygen and other impurities, but also easy to cause harm to the boiler. Oxygen to the water, salt and other impurities cause boiler fouling, corrosion and other problems affecting the safety and energy efficiency of the boiler.

Since more than six months since the direct method for boiler efficiency equipment, heating and hot water supply well, our technical staff also view real-time remote monitoring and control through the use of the boiler to the scene, Baiyun Quan Lake hotel management staff related to our technical staff gave very great encouragement and affirmation. --customer feedback
