3. To maintain the pressure of a gas-fired hot water boiler:
Steam industrial boiler manufacturer in surinam heating stove manufacturers generally have few work process? Steam boiler heating stove manufacturers generally have few work process? 1, the fuel combustion process. The fuel injected into the furnace through the burner, with air mixture entering the furnace to form a combustible mixture, when it reaches the ignition temperature of the fuel, ignition combustion starts and continues until the fuel is exhausted. 2, of flame and smoke, mainly by radiation heat transfer process to transfer the process manner of water in the furnace, convection mainly in an external surface of the metal is heated, the internal heating surface of the metal mainly conducting manner get on. 3, heated water is vaporized and the water cycle process comprises steam-water separating process.
Design requirements for flue of fuel gas industrial boiler manufacturer in surinam roomThe flue should be straight, airtight, less accessories and less resistance, horizontal flue should be laid to maintain more than 1% of the head-up arrangement, as far as possible to avoid the layout along the slope. 2. The flue and chimney of the fuel gas boiler room shall be constructed of steel or reinforced concrete, and the lowest point of the flue and chimney shall be provided with water sealed air and water drainage pipes. 3. The steel plate thickness of metal flue is generally 4-6 mm. When designing the flue, it should be equipped with sufficient reinforcement ribs to ensure the strength and stiffness requirements. 4. The thermal expansion of the flue should be compensated, the compensation amount should be calculated and the correct selection should be made. 5. Heat preservation measures and reliability of steel flue The fixation of the. 6. A boiler corresponding to a chimney should be used in a fuel-fired boiler room. When several boilers are required to share a flue or chimney, the ventilation and suction force of each boiler should be balanced. 7. The necessary thermal and environmental measurement points should be installed in the proper location when the flue is arranged. A single oil-fired boiler with a rated evaporation capacity greater than or equal to 20t/h or a single rated thermal power greater than or equal to 14MW must be fitted with a fixed instrument for continuous monitoring of smoke and SO2 emission concentrations in flue gas. 8. Where smoke easily gathers, and when multiple boilers share a chimney or a total flue, each fuel gas Explosion-proof doors shall be installed on the flue after the boiler, and the position of the explosion-proof doors shall be conducive to pressure relief, and shall be located in a proper position not to endanger the safety of personnel and before turning, when the explosion gas may endanger the safety of the operator. Pressure relief guide tubes should be installed on the explosion-proof device. 9. For some boiler rooms with long flue, the resistance should be calculated and the corresponding blower and induced fan (when there are induced fans) should be selected in order to ensure the smokeless flow. 10. The chimney should consider the corresponding anti-corrosion measures, the flue gas temperature at the outlet of the chimney should be 15 ℃ higher than the dew point temperature of the flue gas, and when the exhaust temperature is lower than the dew point temperature of the flue gas, effective measures should be taken to prevent it. The smoke is poured upside down.
October 23, the 13th China International Wine & Beverage Processing Technology and Equipment Exhibition (referred to CBB2018) kicked off in Shanghai. Fang Group combine fast wine, the actual needs of users in the field of beverage industry, using its own investment to build more efficient industrial boiler manufacturer in surinam test center platform, continuous investment test and adjust them, to bring the latest "Core Europe" series boilers and condensate recovery system solutions exhibition debut.Free Chat
