Secondly, we must pay attention to the air pressure of the gas boiler. When the air pressure in 0.05-0.1MPa, do not forget to issue replenishment, sewerage, water supply system and check the test device to send weapons; when the pressure rises to 0.1-0.15MPa when the need to gauge the trap cleaning ; when the pressure rose to 0.3MPa, to "fire load / small fire" knob to "fire" to strengthen combustion; when 2/3 gas boiler pressure goes up to the rated pressure, you can begin to warm the pipe and aspirated operation, and at the same time pay attention to slowly open the main steam valve to avoid water hammer phenomenon, resulting in adverse effects.
The flue gas temperature during the combustion of an ordinary boiler is very high, about 130 degrees, and it takes away a lot of heat. The condensing boiler condensing combustion technology reduces the flue gas temperature to 50 degrees, condenses some of the flue gas into a liquid state, and absorbs the flue gas from the gas. The heat that becomes liquid, that is, the heat that was originally taken away by the flue gas, is much higher than the ordinary boiler.
In mid-November, Langfang City, Hebei Province continue to promote coal-fired boiler pollution problem, do the atmospheric release 2018 Fourth supervision order, supervision order states: the country, relevant departments directly under the city's control to quickly take a series of measures to prevent and strictly control burning coal boiler pollution problems.
Now is the time winter heating season, but also the critical period of the comprehensive management of air pollution in the autumn and winter season, the coal-fired heating boiler emissions standards are the focus of Langfang City, air pollution prevention and control. To ensure that coal-fired heating to achieve effective control, reduce emissions, minimize the adverse effects on air quality, atmospheric Langfang City Office will join together to focus, determined to win the battle in autumn and winter air pollution of coal-fired boilers.
Steering proposed order, the relevant departments to combine their job requirements for environmental protection, to develop a coal-fired boiler heating energy saving solutions for special work, establish special supervision and inspection mechanism for all heating stations in the main city within the city limits, supervision and guidance heat stand while ensuring a stable discharge standards, to protect people spend a warm winter. Various environmental protection departments will strengthen the tracking and monitoring of emissions of various heating stations, to be serious penalties for excessive emissions of coal-fired boilers, but also will continue to maintain compliance or below the City heating boilers requirements set emission standards for reward and subsidies .
