Key condensing gas power plants boilers efficiencies condensing boiler key point is that condensing technology, is a new energy-saving, environmentally friendly technology; in fact, the principle is not complicated, simple generalization is the flue gas heat recovery through flue gas condensation. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, or even higher, so that water produced during combustion of the fuel (e.g. natural gas: CH4 + 2O2 → CO2 + 2H2O) is in a state of steam superheater in the flue gas, with the smoke. the loss of gas from the chimney. Traditional boiler thermal efficiency is generally only 85% to 91%. The Henan fast condensing gas boiler side, that the exhaust gas temperature is reduced to 35-60 deg.] C, sufficiently recovered latent heat of condensation and sensible heat in the flue gas water vapor, maximum thermal efficiency of up to 108.9%.
Recently, the letters and the ecological environment unit, the letter of "power plants boilers efficiencies air pollutant emission standards" in the "gas boiler exhaust pipe predetermined height of not less than 8 meters, within 200 meters from the building around the radius of the new boiler room chimney when was the tallest building in which the chimney should be higher than 3 meters "requirement questions.
First, the new urban gas boiler chimney should be performed outside the specified height is 3 meters above the surrounding buildings (there are many communities within 200 meters around the building height higher)?
Second, on the 20t / h steam boiler and above, and more than 14MW hot water boiler to be installed pollution-line monitoring equipment, this means that a single 14MW boiler or boiler means the total audience of 14MW?
Third, for example, I have more than 2MW heating station natural gas hot water boiler 7 units, exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment?
A "boiler air pollutant emission standards" (GB13271-2014) states that "fuel, gas boiler stack height of not less than 8 m, particularly boiler stack height is determined by the EIA document approved. Chimney around the new boiler room when there is a building within a radius of 200 meters, the tallest building in which the chimney should be higher than 3 meters. when there is a building within 200 meters around the new boiler house chimney radius, "according to the provisions in the new urban area gas boiler should be implemented", the chimney should be higher than the provisions of the tallest buildings in more than 3 meters, "the.
Two, 20t / h steam boiler and above, 14MW and more hot water boiler must be installed in the line monitoring apparatus contaminants "14MW and more hot water boiler" means a single boiler.
Third, on the "exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment" problem, according to "People's Republic of China Air Pollution Prevention Law" Article 24 "key sewage units should be installed, using air pollutant emissions automatic monitoring equipment, and environmental protection departments to monitor network devices, monitoring equipment to ensure the normal operation of public and emissions information in accordance with law. "provisions, as well as the" State Council on the issuance of three-year action plan to win the blue sky to defend the notice "(Guo Fa [2018 ] No. 22) "outfall height of over 45 meters of elevated source, as well as petrochemicals, chemicals, packaging, printing, painting and other VOCs emissions from industrial sources focus, the focus of sewage into the Directory of key areas should be basically completed by the end of 2019 to install flue gas automatic monitoring facilities, the country should be basically completed by the end of 2020 the automatic installation of flue gas monitoring facilities. "requirements, if the exhaust pipe where the company was listed as key units of sewage, flue gas monitoring facilities should be installed automatically, otherwise, no installation.
Use pressure hot water power plants boilers efficiencies must be sure you know which local initiatives relevant to the choice of experienced personnel to guard, even though pressure hot water boiler is now beginning to achieve fully automatic intelligent operation, personnel on duty but still more important, just like this We can perceive the fastest time in the accidental situation, in order to reduce incur greater losses, in order to hedge against cause accidents.
In gas-fired power plants boilers efficiencies, a circulating pump is generally built. The main characteristic parameters of the circulation pump comprising: a head, flow, shaft power, efficiency and the like. 1. The pump head △ P unit weight of the liquid obtained after the circulation pump mechanical energy, reflected the increase in hydrostatic pressure in the pipeline, units KPa, mbar, mH2o like. Discharged from the pump flow rate Q 2 of the fluid volume or mass per unit time, in units of m3 / h, L / s, Kg / h the like. 3. The prime mover shaft power P shaft power or the transmission power transmitted to the pump shaft, called the pump unit is KW. 4. Efficiency n ratio of the output power to input power referred efficiency of the pump.
Integrated gasification combined cycle (IGCC) plants use a two-step process to create electricity. In the first step, coal is converted into synthetic gas or syngas. In the second step, the gas is used to power a steam turbine, with waste heat from the turbine being recovered to provide additional power (hence the term "combined cycle").Online chat
These boilers are also known as heat recovery steam generators. High-pressure steam from these boilers can be used to generate additional electric power with steam turbines, a configuration called a combined cycle. A simple cycle gas turbine can achieve energy conversion efficiencies ranging between 20 and 35 percent.Online chat
