industrial 12 Ton Vacuum Boiler Manufacturers

The advantage vacuum industrial 12 ton vacuum boiler manufacturers of vacuum boiler is also called negative pressure boiler. The thermal dielectric water of vacuum boiler is high purity water which is deoxidized and descaled and sealed into vacuum chamber. Multiple sets of heat exchangers can be arranged on the upper part of the boiler main body to achieve multiple loops and bear different system pressures. Vacuum boilers do not need to be equipped with plate heat exchangers and volumetric heat exchangers. The heat transfer mode between hot water and cold water in this machine is steam-water condensation heat transfer. The heat transfer coefficient is 4000~4500kcal / m ~ 2 ·℃, which is higher than that of pressure boiler. 50-450kcal / m2 ·℃. More than 10 times. Therefore, the thermal efficiency of the ordinary vacuum boiler can reach over 94%, and because the vacuum medium of the vacuum boiler is not connected with the external atmosphere, the problems of oxygen corrosion and scaling are completely solved, and the service life is long. Vacuum boilers can last up to 20 years or more. Gas-fired boilers in northern residential areas usually use atmospheric or hot water boilers for heating. However, due to its complex system, high operating cost and high risk of scaling and oxygen corrosion, the practical application is less and less. In recent years, the vacuum hot water boiler is getting more and more The more widely used, and because of their excellent safety and pressure heating, they are very suitable for building heat source. The main advantages of vacuum boiler are: there is no explosion danger under negative pressure operation; because of small heat capacity, short heating time, small start-stop heat loss and high actual heat efficiency, the heat transfer of the body not only realizes the pressure operation of the heating system. Moreover, the heat loss of the heat exchanger and the power consumption of the pump are avoided. Compared with the indirect heating system of the boiler heat exchanger, the investment and land area are greatly saved, and the boiler body has a long service life in the closing operation.

Vacuum hot water industrial 12 ton vacuum boiler manufacturerss and pressure hot water boiler What is the difference now a lot of district heating using a unified fired hot water boiler supply, so the performance is that consumers hot water boiler heating is playing an increasingly important role. The most common on the market are vacuum hot water boiler and boiler pressure hot water boiler. The two boiler performance is very different, but many consumers understand both the boiler may have some bias. A, different security present, primarily professional vacuum hot water boiler hot water boiler, a hot water boiler internal negative pressure can achieve the purpose of rapid combustion temperature, while by changing the configuration of a vacuum hot water boiler may be related to atmospheric hot water boiler. So security is more obvious than ever. The pressure hot water boiler in good use, only in part to the use of ventilation, so particularly safe and reliable pressure hot water boiler. Second, since different vacuum hot water boiler less water, less water and therefore require repeated use of the heating heating efficiency of the burner, hot water boilers and atmospheric pressure vessel requires only to open a larger combustor can achieve a good heating effect to be effectively circulating water heating boiler water treatment, as compared to high pressure hot water boiler thermal efficiency and vacuum hot water boiler. Third, the complexity of the different equipment vacuum hot water boiler must be installed on a range of infrastructure, such as a vacuum pump to ensure vacuum. Pressure hot water boiler without the use of a control device to maintain the vacuum. Thus, operation is simple, does not require complicated control apparatus personnel requirements, and the complexity of the boiler plant also has a large advantage can be fully utilized. Sufficient demand for more consumers.

Directly affect the vacuum gas industrial 12 ton vacuum boiler manufacturers energy consumption indicators of the country are a number of reasons to move coal to natural gas roaring blaze of glory, with vacuum gas boiler, greatly weakened contaminated with fine particles, the same time nitrogen oxides and other toxic gases obtained suppressed. Energy consumption index is a measure of normative matters vacuum gas boiler, we look back with a direct impact on a number of reasons vacuum gas boiler energy consumption indicators. By investigation personnel, vacuum gas heat loss generated in the boiler comprises two main parts: the air-fuel ratio combustion and flue gas emissions unreasonable thermal losses. Emission impaired heat loss should be modified in vacuo to rear of the boiler exhaust gas re-use latent heat setter, or better with a type of condensation recovery boiler. Unreasonable fuel ratio faults into: general gas ejector vacuum boiler burner selection, causing air-fuel ratio can not be adjusted automatically. Very many vacuum gas boiler automatic selection of strong non-stage burner, because of unreasonable fuel ratio initiator has the following aspects: the main air-fuel ratio unreasonable comprises two situations: when the atmospheric exceeded, the cool air will be excessively rich the action of heat, vacuum gas boiler initiation energy increase, decrease energy consumption indicator gas boiler in vacuo; when the atmospheric enough, will cause insufficient combustion, vacuum gas generating boiler decreased energy consumption indicator.

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 industrial 12 ton vacuum boiler manufacturerss 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.
