Works gas steam 2 tons vacuum boiler and gas development advantages of a steam boiler desuperheater and pressurized combustion product and the main advantage, gas steam boiler desuperheater role and pressurized combustion gas steam boiler 1. Why not suitable for heating? This is because the pressure of the steam boiler is very high, and the requirements of its pipes and accessories is relatively high. So, on this invisible, it will increase costs and expenses. In addition, the installation of a steam boiler is not very simple. Therefore, based on these factors before reaching this conclusion. 2. What is the role of gas steam boiler desuperheater that? Desuperheaters gas steam boiler is generally in the supply pipe, its main role is to reduce the steam temperature, so as to achieve the desired requirements. Desuperheater in kind, type, and the main surface of the two water-jet. For the surface mounting of formula U-tube is a cylindrical tube body, or a recuperative heat exchanger. Water quality which cooling water is no special requirements, mainly in the scope of the low-pressure steam boiler. 3. Gas-fired steam boiler vacuum boiler combustion whether beneficial? If the negative pressure combustion gas steam boiler, specifically refers to a combustion chamber of the boiler, i.e. the furnace, is less than one atmosphere. The means to achieve it, it is achieved by balancing the ventilation system. Pressurized combustion, which does not improve the speed of the combustion gas steam boiler, or to maintain combustion stability. If the conditions are bad, then seal the furnace, combustion positive pressure will increase insecurity, the work environment is unfavorable. Therefore, only the negative pressure combustion to avoid the above problems. The advantages of gas steam boiler is mainly reflected in what areas? Increasingly serious environmental pollution, to people's lives a lot of inconvenience, businesses are keeping up with the pace of the country, respond to national call, in order to energy conservation. Boiler industry is, to a great old-fashioned gas-fired boilers environmental pollution, with advances in technology, people developed a fuel gas steam boiler can use clean energy, today small to say the next gas steam boiler with you. First, the working principle of the burner heat released by radiation is first absorbed water wall heat transfer, vaporization of water boiling water wall, a large amount of steam into the drum for water separation, the separated saturated steam enters the superheater, by radiation, convection continues to absorb the furnace top and a horizontal flue, the flue gases heat the back pass, and superheated steam to reach the required operating temperature. Second, the use of fuel gas steam boiler is the use of clean natural gas energy, no emissions, waste, clean and environmentally friendly, in line with our energy reduction, sustainable development policies, public praise. Third, gas steam boiler applications range: 1 Civil: food processing, such as making noodles, steamed buns, boiled milk, tofu soups and other snacks, food drying, etc.; dry cleaners, laundry room; hotel, sauna and so on. 2. Industrial use: garment factories, chemical production line with steam; supporting food machinery, chemical machinery; tea fermentation. 3. Laboratory: Laboratory with a small amount of steam, teaching experiment. Fourth, the development of the advantages of gas steam boiler 1, natural gas is a clean energy, no waste combustion, waste gas, compared to coal, oil and other energy sources have the use of safe, high calorific value, clean, and other advantages. 2, gas steam boilers safer than conventional boilers, piping is usually aspirated, crew using gas pressure pre-tuned, fuel combustion more fully, the boiler is stable. Gas-fired steam boilers do not need to register the same as conventional boiler inspection. 3, the higher the efficiency of the hot gas steam boiler. Using the principle of countercurrent heat steam boiler, the boiler flue gas temperature is lower than 150 deg.] C, operating thermal efficiency of 92%, 5-10% higher than the conventional steam boiler. 4, gas steam boiler economy is more prominent. Because of the small water capacity, starts a 3-minute produce saturated steam of high dryness and greatly reduce the warm-up time, saving energy. 1 set 0.5T / H steam boiler using energy in a year can save more than 10 million hotel; fully automatic operation.

Operation of the vacuum hot water 2 tons vacuum boiler operation is very simple vacuum hot water boiler is very simple, bank up a fire, dust, water, ignition thanks to this step, when the bank up a fire is the first cleaning, the ash cleaned and then fill the coal bucket to shut the door on coal. Economic and environmentally friendly vacuum hot water boiler is in line with the needs of social development, therefore, vacuum hot water boiler is also welcomed by the people, and its usage is very large, their own strengths vacuum hot water boiler determines its space development huge. Automatic heating, hot water boiler vacuum meter is automatically displayed temperature and pressure, the secondary vacuum hot water boiler 24 hours can be a stoker, a hot water boiler so that the vacuum can maintain a constant temperature all day, so the use of it will be more convenient vacuum hot water boiler thermal efficiency is very high, can quickly heat up, and there is no dust, of course, and there is no smoke, so that the surrounding environment will not cause any harm to make . Vacuum hot water boiler operation is very simple, he has a very novel appearance, this novel shape can play a decorative role, then there is the structure of the vacuum hot water boiler is also very unique.

A number of factors affecting vacuum gas 2 tons vacuum boiler thermal efficiency of domestic basically coal to natural gas in to work, the choice of vacuum gas boiler vigorous, very large to avoid the contamination of dust, smoke the same time the risk of nitrogen oxides and other gases He won the curb. Thermal efficiency is an important measure of the provisions of vacuum gas boiler, behind everyone together to explore a number of factors boiler thermal efficiency of gas under the influence of vacuum. Through the investigation of the persons concerned, vacuum gas boiler heat loss is probably due to it containing the two: combustion air and flue gas emissions than ideal sufficient heat loss. Emission reduction of heat loss to be fitted at the end of the stack waste heat boiler recirculation gas is arranged in vacuo, or in the selection of the more advanced features FGR boiler. Combustion air ratio is not fully resolved over failure: universal gas ejector-type vacuum boiler with burner, the air-fuel ratio can not be caused to be automatically adjusted. Portion of the gas boiler is a mechanical vacuum blower burner, not over the air-fuel ratio factors initiator has the following points: air-fuel ratio over the probability roughly fall into two categories comprising: when the excess air stream, having a limited excess cold is the action of heat, vacuum gas boiler initiation energy increases, the thermal efficiency of the gas boiler reduced in vacuo; non-compliance when the airflow, burning is insufficient happens, vacuum gas boiler thermal efficiency decreased.
