coal fired hot water boilers

Low temperature corrosion of boiler fuel than coal-fired boilers serious reason these days after another customer asked why there are low-temperature corrosion of boiler fuel serious than coal-fired boilers, small and together we discuss in this article address this issue. When little understanding of the chemistry of you might know equal sulfur content greater body oil and coal, but asked what the low-temperature corrosion of boiler fuel in general it is much more serious than the coal-fired boilers? For two main reasons: a coal-fired boiler, pulverized coal fired boiler in particular, 90% of the coal ash in the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed by fly ash in the flue gas, so that the smoke sulfuric acid vapor in the gas is reduced; coal combustion, about half of the sulfur remaining in the ash. While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content fuel oil in the boiler, about 11% to 12%, combustion can produce about one ton per ton of fuel vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because it contains more water exception table below. Above the dew point of water vapor in the flue gas so that the fuel for two reasons, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1 shown in FIG. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to the fuel, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, not to say in small series, we will come to a low temperature corrosion of boiler fuel ratio of coal-fired boiler this conclusion is serious.

How to protect the evaporation boiler reaches design: In order to stabilize the combustion, if the coal volatiles, reducing the amount of heat necessary to increase the excess air ratio, the boiler furnace flue gas temperature to be reduced and the amount of evaporated water wall decreases, the radiation furnace transducer heat formula indicates, the furnace flue gas temperature to reduce the influence of the radiation heat transfer is the fourth power of the relationship.

Henan difference fast boiler steam boiler steam boiler is a steam boiler with ordinary steam production machinery and equipment, generally used gas, or coal gas as a fuel, there are an electric steam boiler. Henan fast boiler for the inspection of the steam boiler is a steam boiler gas, fuel oil, gas, and it is common conventional steam boiler with the following differences: "steam boiler supervision norms" and the forthcoming introduction in June next year the new pot rules " boiler safety technology to monitor the specifications "are clearly defined steam boiler needs to be regulated by the state. In other words, users looking to buy a steam boiler plant boiler installation and can not be used directly. Before installation To pot seized by the approval and registration required for installation, and the need for inspection on a regular basis, usually one year during the annual inspection. But there are some of the steam boiler does not require registration and annual inspection, the old rules and the new pan pot regulations stipulate a water capacity less than 30L steam boiler is not within the scope of the surveillance. Because the water capacity of 30L water capacity than at home with a water heater are also small, so there is no risk of explosion, we do not need supervision. Henan water capacity fast boiler steam boiler 26L, belongs steam boiler does not require supervision. Steam boiler explosion hazards generated is amazing. In many steam boiler explosion in the boiler room were razed to the ground, the annual explosion of a steam boiler will be the first to cause casualties and significant economic losses. Henan fast boiler steam boiler is to achieve the ultimate, the boiler body through the scientific design, water capacity is very low, only 26L, itself, there is no risk of explosion on security. The thermal efficiency of conventional steam boiler is only 80%, while the party Henan boiler thermal efficiency of fast gas steam boiler can reach more than 93%. Henan plus energy-saving system fast boiler control systems, the actual energy savings up to 30%, running down a year could save hundreds of thousands of operating costs. The Henan fast boiler steam boiler without boiler room, an area itself is small, you can put in the basement or roof, it can also be placed directly next to the device requires the use of steam. Saving the cost of laying pipe network construction costs and the boiler room, a significant reduction in the use of the initial investment.

Handan: Before the end of October to complete the transformation of more than 10 tons of steam gas boiler burning low nitrogen

A few days ago, Handan City issued "on the deadline to complete the nitrogen oxide gas boiler governance" (the "Notice"), clear objectives, tasks nitrogen oxides governance gas boiler, expected to be completed more than 10 steam tons of gas before the end of October this year, low NOx combustion boiler reconstruction. "Notice" to the objectives and tasks of nitrogen oxide gas boiler control, time requirements, safeguard measures have been clearly defined.

First, the implementation of the transformation of ultra-low emissions

By the end of June 2020, the existing non-electrical gas steam boiler, hot water boiler, Stoker stoker furnace and completed the transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxides reach 5mg / m³, 10mg / m³ , 30mg / m³, the new gas combustion boiler synchronizing means and is mounted low nitrogen meet emission standards. 20 tons of steam / hour or more gas-fired boiler installation atmospheric pollution automatic monitoring facilities, and networking with the environmental protection department, install a distributed control system (DCS system). 20 t steam / hour to be mounted gas-fired boiler exhaust gas nitrogen oxide analyzer.

Second, the phased completion of the task of transformation of governance

10 before the end 2018, to complete the combustion of the transformation Boilers nitrogen over 10 tons of steam, to complete the 1-10 tons of steam (having a steam tons and 10 tons of steam) combustion transform low nitrogen gas boiler before the end of October 2019, 2020 at the end of 6 before completing the transformation of low-nitrogen combustion gas steam boiler 1 ton. Counties (cities, districts) according to the actual situation, to be completed in advance of nitrogen oxides governance gas boiler.

Third, both subsidies and penalties

"Notice" requirement for acceptance of project management, to give appropriate subsidies comprehensive financial subsidies to control air pollution. Due to the unfinished task of governance be ordered to stop production of governance. For excessive emissions, fraud, unauthorized outage environmental protection facilities, waste-water treatment snuck issues such as rectification and punishment according to law; wrongdoing, be held criminally relevant personnel.
