Gas-fired heating is to protect human health and indoor warm natural gas boiler 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 wns efficient horizontal steam boiler 2 ton per hour in karshi 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.
Steam Gas Gas Desulfurization to achieve excellent results steam oven gas steam oven must sample tests, the thermal conductivity was measured quality of appearance, flash point, viscosity, acid, water, and carbon residue, provided with heat transfer fluids plant proof mass It is consistent with the book, but also provide the basis for future changes in the operation of medium quality monitoring. Means passing the tests of the gas-steam heat transfer fluids using pumps to transfer fluids within the furnace and the injection of hot expander. When pumps heat transfer fluid to the injection system, should check again the furnace, heating equipment, piping system drain valve, drain valve is closed, in order to avoid loss of heat transfer fluids. While the exhaust pipe and the valve opening on the furnace one by one, to exclude air, until a closed gas steam flows. It stops when the oil level gauge appears on the expander injection heat transfer fluids, and then start the circulation pump, for circulating cold. Existing gas steam oven dry dust, do not meet wet desulphurization process of flue gas CWS humidity, water vapor in the flue gas as coal-water slurry up to 36%, some as high as 40% or more water content of coal-water slurry, If we consider only the dust and sulfur dioxide that is not enough. Arts gas wns efficient horizontal steam boiler 2 ton per hour in karshi company after multi-party experts to study, test, develop a dusting product, the successful use of coal-water slurry plenty of water in the flue gas as a carrier, by cooling, reducing condensation, dust and sulfur dioxide capture down, to achieve excellent results gas desulfurization steam oven. The effect of dust reaching the user's satisfaction. Gas welding gas steam oven must be operated by welders holding boiler and pressure vessel certification of welders. Welding dimensions meet the design drawings and process documents, bead height is not less than the base material, the base material with a smooth transition. Gas fuel gas steam oven weld and heat affected zone no cracks, holes, craters and slag. Weld undercut hole deeper than 0.5mm, the total length (the sum of both) is not more than 1/4 of the circumference of the tube, and not more than 40mm. Construction of gas steam oven strict compliance with welding procedures and other relevant standards and regulations, and make construction records welded to record the record.
The "national industrial energy-saving technologies and equipment Recommended List (2018)" key recommendation "premix wing-type vacuum condensing hot water boiler" There is a beautiful name - Thalia T6, through the rational use of the U-shaped smoke tubular, cross-wing type tube design structure, and heat transfer at the same time meet the thermal requirements, reduced to 33% of the entire area of the boiler can be placed in a small area in the boiler room. At the same time the use of advanced industry premix combustion technology, will reduce nitrogen oxide emissions to 18 mg / cubic meter, well below the most stringent air pollutant emissions of Beijing, Tianjin, Zhengzhou and other cities 30 mg / cubic meter standard.
Introduction of fuel gas-fired boiler fuel gas-fired boiler Product Description: Fuel gas-fired boiler fuel but also refers to both gas boiler. Only boiler fuel called oil-fired boiler, gas boiler can only be called a gas boiler. If the configuration boiler fuel gas or dual fuel burners, then the boiler is oil or gas boiler. Fuel gas-fired boiler is a more general concept, fuel gas-fired boiler is divided into water boilers, hot water boilers, wns efficient horizontal steam boiler 2 ton per hour in karshis and thermal oil boiler, according to their own use to select a different fuel gas-fired boiler time of purchase. Fuel gas-fired boiler is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. Oil injected into the furnace, if the gas and air mixture within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a distribution box, it may also be assembled and medium-sized factory. Advantages: the advantages of fuel gas-fired boiler: 1), high efficiency boilers. 2) simple structure. 3), supporting the use of simple auxiliary. 4), and the whole intelligent automatic control system with multiple levels of protection. 5) equipped with burners (blower) and a flue muffler system, reduce the noise of the boiler operation. 6), should be equipped with automatic dosing unit, the water treatment device. 7), with other monitoring and limiting device should be at least 24 hours to ensure that the boiler safe operation of unsupervised. 8), before starting the first boiler is purged before ignition function automatically. Boiler maintenance: (1) Dry regimen: the boiler furnace shutdown to discharge water, the inside completely remove the dirt, rinse, drying in the furnace with Weihuo (be careful not to fire), and a diameter of 10-30 mm in size massive quicklime installed sub-plate, placed in the drum, without contacting the metal with lime, quicklime weight, calculated to the drum 8 kilograms per cubic meter volume, then all manholes, hand holes pipe valve closed, checked every three months, such as lime ingredients like broken, i.e. the need to replace, should be re-run the boiler and the lime disk unloading. (2) Wet regimen: After Shutdown of the water discharge released, the internal completely remove the dirt, rinse, refill treated water to the full, the water was heated to 100 deg.] C oven, so that the water discharge gas outside of the furnace, then close all the valves, cold climates where moisture can not support the use of law, so as not to damage the boiler furnace water freezes. Structural features; fuel gas boiler is different from the coal-fired boiler, which requires the use of a burner fuel into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. If the hydrocarbon injected into the furnace with the air mixing within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a chassis, the assembly may also be medium-sized factory. Now the main element and the pressure connection of the fuel gas boiler are as follows: 1, the main fire tube boiler pressure parts: the boiler shell, a tube sheet, furnace, smoke pipe; 2, the main pressure element water tube boiler: drum (drum), water wall boiler bank, serpentine tube header; 3, the main pressure connection element fuel gas boiler: the main welding, expansion may be part.
