Introduction condensing 2 ton boiler tajikistan: condensing boiler efficiency is the use of flue gas condensation heat recovery boiler to absorb latent heat from exhaust tail and the sensible heat released by condensation of water vapor, to achieve the purpose of improving the thermal efficiency of the boiler. Thermal efficiency of the condensing boiler Analysis: conventional boiler, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated without considering the heat loss of latent heat of vaporization of fuel in the high heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat of condensation and sensible heat in the flue gas water vapor. Flue gas-fired condensing heat recovery steam boiler flue gas volume components typically produce 15% to 19%, the water vapor content of the oil-fired boiler flue gas is 10% to 12%, much higher than in coal-fired boiler water vapor content below 6%. Currently the thermal efficiency of the boiler are low calorific value calculation, although nominally higher thermal efficiency, but because of high natural gas, low calorific value difference of about 10%, the actual energy efficiency to be increased. To take full advantage of energy, reduce exhaust gas temperature, flue gas heat recovery physical, when the wall surface of the heat exchanger flue gas temperature below the dew point temperature, water vapor in the flue gas will be condensed, releases latent heat, low and high 10% calorific value difference can be effectively utilized.
Ordinary gas 2 ton boiler tajikistan obvious advantage is the relatively low price, which is most of the reason customers choose it. Just use the boiler is not mandatory for low nitrogen emissions, you can directly select the ordinary gas boiler, this enterprise is also very friendly.
Boiler equipment belongs to special, complicated structure design, operating environment is more severe, during use, is often influenced by temperature and pressure stresses and alternating. If long-term use down, inspection and maintenance neglect 2 ton boiler tajikistans, boiler operation will likely cause reduced efficiency and security risks. Once accidents, often fatal. But many companies and personal security awareness is not strong, it is still a long time to run the boiler inspection, inability to control the operation of the law of the boiler, there is a big security risk.
Recently, Gaoyou City, Jiangsu Province for coal-fired boilers Market Authority has embarked on a comprehensive inspection operations, according to "comprehensive coverage, thorough investigation, replicability, results-oriented" principle, the use of coal-fired boiler business diagnostic investigation, and effectively eliminate security risks.
City Supervisor Bureau focus on verification of the actual use of coal-fired boiler units, using the address, use, heating, technical parameters, test status, filing one by one, do on-site inspection records strict accordance with relevant provisions, retained image data. To phase out coal-fired boilers to be found in the inspection, and urge the relevant units to implement the safety responsibility, and return in time for retirement procedures using the registration certificate. So far, the council has issued eight safety supervision instructions to complete the verification of the use of 14 units of 45 coal-fired boilers and filing, of which three units have been deregistered 15 piece of equipment.
How discharge effluent gas 2 ton boiler tajikistan 1) to open the inner discharge water valve; (2) Slowly open the blowdown valve external to warm up and sewage pipes; (3) an external switch repeatedly discharge water valve, slow flush pot scale, scale so as discharged; (4) the inner blowdown valve closed, these two discharge water stored between the water drain valve; (5) external discharge water valve closed, the discharge sewage terminated.
