The difference between fuel gas condensing boiler residentials and oil-fired boiler fuel boiler is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, methane, etc.), depending on what fuel fired boiler combustion device called , a configuration called gas burner boiler gas boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference lies in the use of fuel burners burn anything.
How to improve the thermal efficiency of gas steam condensing boiler residential steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased tail gas steam boiler heating surface of, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.
Brewery condensing boiler residential burners should choose how to select the furnace temperature and pressure. Recorder manufacturer must indicate what type of device it belongs to the device, the furnace pressure is positive or negative, pressure is how much, how high the temperature is. Because different types of furnace temperature, different structures of the burner, use of different materials, selected as a high pressure burner furnace burners to overcome the low pressure furnace burners. When the calorific value of gas pressure is selected as the fuel gas, due to the variety of different calorific value of gas, the pressure is inconsistent, so the choice of the manufacturer and described in the fuel burner type, the number of heating value, to select the appropriate number combustor pressure, in order to avoid the risk of an incorrect selection. For this mode the device for adjusting the required temperature accuracy can select some fire (only one burner in a secondary operating mode Fire (burner operation mode to fire small, the work of two point mutations, two operation switching point mutation) in operating point), progressive (small fire, small fire) mode. Operating point, switching between the two stable operating points progressively. Burner adjustment (at any point within the operating range of the combustor burner combustion mode can be left behind, to balance the requirements for the heater system output). If you choose to spray heavy oil, heavy oil burner may be the result of a mechanical fuel atomizer, F middle area atomizer burner and different geographical environment, different environments for different viscosity requirements of the burner differ .
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.

An oil-fueled central heating system works in the same way as a gas-powered central heating system. The best oil boilers use oil to heat water, heating your home via radiators and sending hot water to the taps. The biggest way an oil boiler differs from a gas boiler is, because youre off the mains gas grid, and you dont have mains gas supply feeding constant gas to the boiler, you will need to store oil at or outside of your property.Learn More
