Seven, strengthen supervision clean heating work. According to "planning" urged all localities to innovative regulatory measures and means to closely follow the progress of work, mastery goal of task completion and work to promote the practical difficulties, in conjunction with the Energy Bureau sent regulators to organize the supervision and inspection and appraisal. All localities must submit the plan to the Energy Board by December 15 to submit the report within two weeks after the end of the heating season.
The main structure of a natural gas boiler consists of a boiler shell, a tank, a switching chamber, a smoke pipe, etc. The boiler is suitable for various fuels such as light oil, heavy oil, natural gas, liquefied gas, and so on. The boiler has a reasonable structure and a double-layer reverse burning. It is beneficial to make full use of flue gas, and has the characteristics of small area, convenient installation and good steam quality. The working principle of natural gas boiler is: the water enters the boiler through the inlet, the water quality that meets the heating standard after the boiler is heated, the water is fed into the indoor radiator through the circulating pump, the heating is heated by radiation and convective heat transfer, and the water flowing through the radiator is flowing through the water of the radiator. Go back to the boiler and heat it up, and then go back to it. It flows into the radiator, so that it circulates over and over again. Moreover, the natural gas boiler system can also provide users with hot water to meet its basic needs, the temperature of the water quality in the boiler and the indoor temperature, after temperature sensor processing, the temperature signal is transmitted to the single-chip microcomputer. Through the corresponding driving circuit, to adjust the size of the corresponding pipe valve, and then by controlling the water quantity to control the water temperature, to achieve the purpose of heating, the user can also select the appropriate circulation pump according to the size of the heating range. This is also more economical and convenient.
Matters needing attention in installation of Gas-fired BoilerGas-fired boiler also says that gas-fired heating boiler is a kind of boiler which uses gas combustion to heat water to satisfy people's heating. It belongs to the category of domestic boiler. By gas-fired heating boiler we usually refer to gas-fired atmospheric hot water boiler, gas including natural gas, liquefied gas, city gas, coke oven gas, biogas and so on. There are explosion-proof doors on the rear of the fuel-fired boiler or on the smoke pipe, and the position of the explosion-proof doors should be conducive to the discharge of the explosion. In cases where explosive gas may endanger the safety of operators, a pressure relief guide tube shall be installed on the explosion-proof door. The installation of boilers, auxiliary machines and water treatment equipment shall be in accordance with the technical requirements of the equipment manufacturing plant. . The equipment foundation must wait until the equipment arrives and checks correctly with the design drawing before construction. 3. When installing the equipment, avoid the equipment, and the installation material should be stacked on the floor. When using building column, beam lifting equipment, the bearing capacity of beam and column must be verified in advance. 4. After installation of oil, gas, hot water and steam pipes, the pressure test acceptance shall be carried out according to the Code for Construction and acceptance of Industrial Metal Piping Engineering GB 50235 / 1997.
About the kind of horizontal type fired steam boiler with high quality fuel oil boiler steam through the next, there are many main purpose, main features, a brief Automatic fuel gas steam boiler. A: The main purposes: food processing, printing and dyeing, pharmaceutical production and provide steam to provide steam sterilization, medical institutions, enterprises and institutions to provide steam for the other, the hotel's heating Automatic fuel gas steam boiler, the heating can also provide domestic hot water tank by . Second: The main features: 1, with central back burning structure, a large volume of water and gas boiler space, adaptable load capacity. 2, the indoor micro-pressure flame automatic steam boiler fuel combustion, the flame is fully extended, enhanced heat transfer, thereby reducing convective heating area, reducing the cost of the boiler. Smoke flow resistance is small, low-power consumption operation, operating cost savings. 3, in addition to the conventional four level height control, an additional level detector 5, the detection bit will stop when the boiler water, alarm, to ensure safe operation of the boiler. 4, the front smoke box special heat insulation materials, high temperature, low thermal conductivity, good anti-radical quenching heat capacity, greatly extending the life center back burning boiler before the smoke box, the furnace insulation is multilayer glass wool , light weight, low heat loss. 5, automatic oil-fired boiler steam pressure is controlled by Danfoss and Danfoss pressure controller and pressure transmitters joint control, pressure controller is responsible for ultra-high pressure interlock protection, prohibits burner working and alarm; pressure transmitter responsible for combustion engine to work to achieve some or all of control, to achieve automatic control of the exact steam pressure and steam pressure in the pressure range provided by a touch screen, detecting a pressure up to 0.002 MPa, more accurate pressure control. Thus avoiding a pressure controller general requirements of the production and the high vapor pressure of low pressure gas boiler or the actual requirements of the production of high pressure and low pressure gas boiler can not meet the disadvantages of the production requirements. 6, flue gas condenser fast side (optional) by the national utility patent, requires efficient use of steel-aluminum sheet Chi spiral tube heat exchanger, heat transfer surface is sufficient, the small side of the flue gas resistance of the system to meet the general burner. With flue gas condenser heat boiler efficiency can be improved more than 8%, the fuel gas savings of nearly 10%. These are the simple on automatic steam boiler fuel introduction want to be useful.
