Steam boiler thermal efficiency of gas-related factors and ignition tests: on specific types of boilers, how to avoid a steam boiler explosions for gas this kind, because it is one of the boiler product site, so its knowledge and understanding, it is necessary because only then will we be able to fully understand all the products website, and do not miss any of them. Furthermore, to allow yourself to have a good learning. 1. Gas-fired steam boiler, whether vertical and horizontal points? In addition, their characteristics, what is? Gas-fired steam boiler, which is vertical and horizontal points, and this is very positive. Vertical gas steam boiler, which is a two-pass structure is such that the fuel can be sufficiently combusted. Moreover, its small footprint, high thermal efficiency, can effectively reduce usage charges. Horizontal gas and steam boiler, which is a three pyrotechnic return pipe structure, the advantages thereof, the high combustion efficiency, low exhaust gas temperature, and energy saving can be achieved.
What issues need attention when heating boiler cleaning? Heating boiler and life quality not only has an important relationship, in fact, more important is the usual maintenance, such as maintenance and cleaning is a very important factor to enhance heating boiler life, how to clean has a very important influence on the heating boiler. We buy them from the market to remove scale, rust items mainly by food acid, synergist, metal protective agent composition. Has a strong penetration of scale industrial and residential boilers, how to avoid a steam boiler explosions, heating boilers, etc., rust and sediment, and dissolved peel effect, washed bright as new, non-toxic, harmless and safe to use. Features: First, strong: stripping and dissolve quickly scale, rust, bacteria and algae and other deposits, and turn it into a water-soluble or suspension readily discharged. Second, security: no conventional pickling bring the smoke, hydrogen embrittlement, highly corrosive and burning and irritation on the human body. Product features: fast dissolving calcium carbonate, magnesium carbonate, calcium sulfate, calcium silicate, and iron oxide scale and other ingredients; metal corrosion, non-toxic, rapid and complete removal of scale adhering to the inner walls of the boiler. Usage: one, the detergents diluted with water in 1:10 injection boiler inlet; Second, the top up the water to the highest level, waiting for 4 hours, the reaction scale and full scale remover solution; third, open waste outlet, drain cleaning fluid; IV injection to clear water rinse, cleaning cleaning work is completed. How to clean the heating boiler has a very important impact on our boiler when cleaning the boiler note that the above considerations, we can well enhance the service life of the boiler
According to our learned Wenzhou Municipal People's Government on February 12 issued a notice "Wenzhou Blue Sky win the Battle of action to implement the program (draft)", the details are as follows.
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, safe and efficient development of nuclear power, optimizing 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 the State to win the Battle of the sky 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.
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. In the premise of protecting the power system security and stable operation of 2020, to accept the outgoing power levels to at least 38%.
Consolidate construction achievements combustion zone ban, increase efforts to eliminate small coal-fired boilers. According to the National to win the Battle of the sky 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 out of coal-fired tea furnace, operating a stove, grain storage and drying equipment, etc. facilities; basically eliminated the city's 10 steam tons / hour and 35 steam tons / hour of coal-fired boilers; 35 steam tons / hour and more polluting fuels and energy-efficient boilers to complete the transformation of ultra-low emissions; low nitrogen gas boiler basically completed the transformation; city built-up area of biomass boilers implement ultra-low emissions transformation.
Condensing hot water boiler enough for the sensible and latent heat in the flue gas is completely absorbed than ordinary boilers: condensing how to avoid a steam boiler explosion more environmentally friendly than conventional gas boiler, has been forced to use in Europe, and to promote our country is still in its infancy. Condensing boiler compared with ordinary gas boiler, mainly in the "condensed" word above, condensing boiler can be sensible and latent heat in the flue gas is completely absorbed, then it is how to do it?

Nov 15, 2014 · Fuel explosions can cause damage to the boiler tubes and interior shells, and can trigger failure of the structure, leaks, a secondary shell failure or steam explosion. A boiler explosion can be very damaging because it allows for steam to escape. Steam takes up 1,600 more room than water. When steam is allowed to escape, it all goes out at once. The pressure produced from this can be compared to the detonation of explosives or gunpowder. Where did boiler explosions happen in the past?Learn More
