how to choose the best condensing boiler
As one of Beijing's air pollution emission standards of the most demanding urban, environmental control is very strict. Beijing primary school campus Emerald City as one of the cradles of socialist culture successor, in terms of the quality of students' learning environment is put emphasis on one hundred percent. October 2017, Beijing primary school campus Emerald City with my company, signed a two Thalia T6 series vacuum hot water how to choose the best condensing boiler for winter heating use.
Industrial gas condensing how to choose the best condensing boiler works and the core technology of industrial gas condensing boiler, by definition, it is a condensing gas boiler. Currently, condensing gas boiler can be divided into commercial gas condensing boiler and condensing gas boiler industry. Products are also different from the horizontal condensing boiler and condensing boiler vertical. The most important is to realize the nature of condensing boilers condensing technology. The key industrial condensing gas boiler condensing boiler key point is to use the condensing technology, which is a relatively new type of energy-saving and environmental protection technology. In fact, the principle is not complicated, the simple conclusion is that to recover the heat energy of the flue gas through the flue gas condensation. In general, the traditional boiler thermal efficiency of only 85% or 91%. The exhaust gas boiler condenser temperature was lowered to 35-60 ℃, full recovery of latent heat and sensible heat in the flue gas water vapor. Maximum thermal efficiency of up to 108.9%. Industrial works condensing gas boiler works condensation gas boiler is the hot flue gas discharged from the combustion boiler (typically from about 140 deg.] C) recovering the energy, the temperature of the exhaust gas after recovering only about 60 ℃. Thus, the thermal efficiency is improved about 10%, about 10% gas savings. Meanwhile, in the process of energy recovery, it is also possible to reduce harmful emissions, reduce environmental pollution.
How to clean gas how to choose the best condensing boilers: gas boilers after a long run, inevitably there will be scaling and corrosion problems. Hot water boiler boiler assembly PC-style controller, all functions are stored on a smart chip, intelligent boiler, digitization, automation, humane, intelligent control of boiler water temperature, water temperature reached the heating automatically stop; large screen fonts display temperature, boiler water temperature at a glance. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing the main reason of boiler fouling user fee is water containing hardness components, continuous and concentrated by evaporation under the high temperature and pressure, the furnace a series of physical and chemical reactions, form a hard, dense fouling on the heating surface, resulting in heat transfer effect and corrosion under the scale reduction factor. This will cause the boiler waterwall furnace heat absorption of the boiler furnace exit decreases and the temperature is increased, the loss increases boiler. Meanwhile, the water wall fouling, reduced heat transfer effect, could lead to water wall temperature, resulting in burst pipes water wall, affect the safe operation of the boiler. Fouling is a bit hazards in the boiler, the boiler is the main reason for the accident. Harm the main problems: wasting a lot of fuel: As the thermal conductivity of scale is only one-tenth of steel, when the heating surface fouling, heat transfer is impeded. In order to maintain a certain boiler output, it is necessary to improve the fire side temperature to heat loss caused by smoke and outgoing radiation.
Blowdown rate: 0.1% -0.5% General how to choose the best condensing boiler evaporation.
Emission Location: the water from the bag is introduced to the expansion of a given row. After decompression, and secondary steam expansion separated waste hot water. Secondary steam into the atmosphere or utilized as a heat source, waste hot water through the general sewage into the sewer system cooling pool. Boiler blowdown water and saturated with water at the same pressure and the working pressure boiler, before the throttle valve is provided with periodic blowdown pressure is reduced, so that the periodic blowdown expander expansion cooling, secondary steam is separated.
