high efficieny hot water boiler

Measures to prevent low-temperature condensing gas high efficieny hot water boiler corrosion: Due to the unique natural clean, environmentally friendly combustion characteristics, is widely used today. Gas hot water boiler has also become the most widely used of a boiler, with good heat performance, easy operation advantages. But inevitably, gas hot water boiler also has some flaws, corrosion problem is one of the most serious shortcomings. Gas hot water boiler corrosion are mainly low-temperature corrosion and chemical attack types. This paper focuses on low-temperature corrosion were told. Low temperature corrosion due to corrosion caused by acidic substances, natural gas produced in the combustion process of carbon dioxide, after encountering the condensed water condensed by partial hydrolysis of the carbonate, which is the cause of low-temperature corrosion. As the carbonic acid is weak acid, and volatile, so the low-temperature condensed gas hot water boiler corrosion problems are often overlooked by people. But long-term use down the corrosion problem becomes more obvious, gradually pose a threat to the safe operation of the boiler.

1.4MW heating boiler for Residential heating

Heating boilers is a heating method used in many places in cold winters. The most common heating boiler is a hot water boiler. The hot water flows through the pipeline and dissipates heat to increase the indoor temperature for heating purposes. Steam boilers are also used in some cases. However, steam boilers are mostly used for heating and power generation at the same time. At present, urban residential heating has become a requirement. Then the 1.4MW boiler is used for residential heating. How much heating can it be?

Accelerate the implementation of the relevant arrangements for the deployment of national, provincial and develop natural gas and other clean energy. According to Yi gas of the gas, the electric power should be the principle, and actively guide enterprises to implement energy clean energy alternative, 2020, the basic completion of provincial trunk pipeline construction, the basic realization of natural gas every county, to further improve the urban and rural distribution pipe network construction , the city's natural gas consumption reached 570 million cubic meters, the proportion of non-fossil fuels in total energy consumption to reach the provincial requirements. Orderly development of hydropower, nuclear power is safe and effective, optimized wind energy, solar energy development layout, local conditions to develop biomass energy, geothermal energy and so on. Where the conditions of availability of resources, to encourage the development of county biomass cogeneration, biomass briquette boilers and biogas. Orderly development of natural gas peaking power plants and other interruptible user, in principle, to new natural gas cogeneration and gas chemical projects. Continue to implement the priority generation and purchase of electricity system to ensure the city's renewable energy generation full protection of the acquisition.

Strict new coal project access, the implementation of the reduction of coal instead. According to Blue Sky to win the Battle of three-year action plan calls for no new 35 steam tons / hour high-polluting fuel boilers. By 2020, the city's coal accounts for the proportion of total energy consumption fell to 42.8% or less, the city's total coal consumption decreased by 5% compared with 2015. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal in 2020, the city's electricity and central heating coal proportion of total coal consumption reached provincial requirements. Continue to promote alternative energy coal and oil, replace reached the provincial requirements.

Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance, according to plans to phase out other coal-fired thermal power generating units. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. Strict control of new coal-fired units installed capacity in the region rely on new clean energy generation and transmission to meet outside the main electricity consumption.

Consolidate construction achievements combustion zone ban, increase efforts to eliminate small coal-fired boilers. According to Blue Sky to win the Battle of three-year action plan calls for phasing out the 10 steam tons / hour and coal-fired boilers, the county level and above urban area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities ; 10 basically eliminated city steam tons / hr steam 35 tons / hour of coal-fired boilers; 35 t steam / hour and more polluting fuels and ultra-low emissions boilers complete energy transformation; low-nitrogen gas boiler is substantially complete transformation; urban built District ultra-low emission biomass boilers implement reform.

Compared with ordinary boilers condensing boilers more environmentally friendly. Gas will produce large amounts of carbon dioxide in the furnace of the combustion, nitric oxide and sulfur dioxide little. These products of combustion flue gases emitted to the atmosphere with the air can damage the environment, it is more intuitive greenhouse effect and acid rain. Condensed in boiler flue gas while water vapor is condensed, the flue gas emissions of hazardous substances decreases. From an environmental height, the condensing boiler with respect to the ordinary boiler to be encouraged to use more. Difference V. price, service life
