panimatic rolling tubes of the steam boilers

Brief Introduction of fuel gas-fired boilers of steam condensate heat recovery boiler flue gas volume of the component is generally 15% to 19%, oil-fired boiler flue gas water vapor content of 10% to 12%, much higher than the coal-fired boiler generating water vapor content of the flue gas 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. 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. Condensing technology as a new type of environmentally friendly energy-saving technology, its principle is not very complicated, simple summary of what is recovered by condensation equipment hidden in the flue gas and water vapor in the latent heat. In conventional boilers, 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.

Why is the pH of the hot water boiler important? In addition, is there a decisive factor in the heating area of ​​the hot water boiler?

Combined with China's current situation, the provinces and cities have environmental requirements. General requirements for a gas-fired boiler increases: low nitrogen. Condensing technology now used in the fast side is one of the primary techniques to reduce nitrogen oxides (abbreviated NOx) in. If NOx emissions do not meet state regulations, it is absolutely not allowed to be used, even after running for some time, EPA will be ordered for low-nitrogen transformation or elimination process.

To ensure the safety of special equipment such as boilers, in normal use, to further promote the comprehensive management of environmental pollution, since April this year, Khorgas Market Supervision Administration of Quality Supervision Bureau for the joint Yili area within the jurisdiction of Khorgas , launched a special safety inspection activities boilers.

Law enforcement officers to be included within the jurisdiction of the major hazard of 12 boiler units of a total of 21 boilers individually conduct a special inspection, focus on examination of the "three implementation, two certified, a test, a plan," the implementation of a detailed view of boiler safety management system, run records.

Test results showed that most of the boiler unit security management more standardized, but there are still some units use boilers run records were incomplete, part of the boiler has to inspection cycle, has been scrapped or dismantled boiler is not write-off and other issues, law enforcement officers to issue on-site boiler sealed, and ordered boiler unit for rectification.
