PRODUCT INTRODUCTION fuel gas-fired fired boiler heating per kg of steam fuel gas-fired boilers and coal-fired steam boiler is not the same, gasoline and diesel and gas-fired burner must be poured into the fuel to the boiler furnace using a combustion chamber rather than grate facilities. Since the fuel gas-fired boiler is not easy to cause the fly ash lit, so no oil or gas boiler slag removal equipment. If mixed with air or exterminate within a certain range, it is introduced into the furnace petrochemical and gas easily the explosive. Thus, any gasoline and diesel and gas-fired boilers must be selected and automatic combustion control system. Compact boiler fuel gas, and the small boiler exhaust, drainage, control and auxiliary equipment installed at the distribution panel, and produce large and small boiler assembly. Fuel gas-fired boiler safety valve installation key point describes the installation of fuel gas-fired boiler safety valve sure to carry out in accordance with reasonable installation process, to prevent wrong and lead to risk. Fuel gas-fired boiler safety valve installation should pay attention to what matters? The following is a brief description: 1 oil-fired boiler safety valve having a lever bar to avoid self-weight and the mobile device guide body defining deviant lever, the spring valve lift handle and avoid the need for screw adjustment means random twist. 2. Rated evaporation than 0.5t / h gas boiler safety valve should be arranged at least 2, Rated evaporation gas boiler should be equal to or less than 0.5t / h, fitted with at least one safety valve. Separable economizer outlet and a steam superheater outlet valve should be installed. Sectional area of the connecting pipe between the boiler safety valve 3. Fuel gas boiler can not be lower than the imported cross-sectional area of the valve. If several valve mounted on each stub is directly coupled to the drum, the passage sectional area of the stub is less than 1.25 times not all of the area of the exhaust valve. 4. Oil and gas boiler safety valve should be mounted vertically in the height of the boiler drum and the header. Can not be mounted between the valve and the steam outlet conduit and the valve drum or header. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25 mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20 mm. 6. Fuel gas boiler safety valve should normally be established an exhaust pipe, the exhaust pipe should be directly connected security grounds, and there is sufficient cross sectional area to ensure the smooth flow of the exhaust gas. The bottom of the valve should be equipped with an exhaust pipe connected to the drain of a safe place. Valve must not be installed in the exhaust pipe or drain pipe.
Gas-fired heating is to protect human health and indoor warm natural gas fired boiler heating per kg of steam with natural gas, LPG, city gas and other gaseous fuels for fuel combustion in the furnace put out heat, heat the pot of water, and it vaporized into steam the thermal energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source. Gas-fired heating is to protect human health and indoor warm, so the choice of natural gas boiler when security issues are important, but the quality can not be ignored, and only with good quality, just more comfortable when in use, some of the services also can do better, choice of heating is customer satisfaction. Learn natural gas boiler certainly need to know the sales of the product, and if it shows good reputation natural gas boiler in the comprehensive aspects are still very good, worthy of consumer choice, performance, and thermal energy conversion can consult, when such use was not there will be problems when installed, do not worry voltage is not enough. Gas boiler shutdown method: after stopping a powder, a duct for 5 minutes and then purged to stop the gun. Oil gun should be purged one by one, not at the same time purging multivessel oil gun. After completion of purging gun oil, natural ventilation of the boiler furnace 5 to 8 minutes, 20 ~ 30% of the air volume is not less than the rated load. To exclude combustible material remaining in the furnace. The fuel gas-fired steam boiler can be divided into natural gas, city gas steam boiler, a steam boiler coke oven gas, LPG and steam boiler; according to the structure can be divided into vertical and horizontal steam boiler steam boiler. Gas boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving , more economical, and a waveform furnace threaded pipe structure, i.e. increase the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.
In mid-March this year, Shenyang City, the first fired boiler heating per kg of steam industry issued emission permits.
