low heat loss commercial hot water boiler
Mounting a few points due to the volume of the gas steam boiler suitable gas steam boiler is relatively large, and the heating efficiency, so to choose the best products. Installation of the boiler prior to the sales company symmetric, or mounted directly by the direct manufacturers to ensure proper installation. As gas steam boiler using a multi-combustion chamber to improve the co-combustion heating efficiency, so it's full of burning very important, and is directly related to the adequacy of the installation of gas steam boiler and combustion, the following small series to tell you install a gas steam boiler a few key points. First, you must make insulation products meet the description requirement, although at the time of sale of gas steam boiler, the manufacturer will be shipped with related installation method, but the construction of a gas steam boiler is not as static, so to install according to the drawings and technical documents prior to installation Contact site construction environment. All in all, we must ensure that refractories gas steam boilers, and thermal insulation products and drawing standards inside and outside of the match. Second, important to note that the vertical rollers and the row spacing is generally the most professional installers gas steam boiler before installing the gas steam boiler, middle and late stages are calibrated and corrected size furnace building, but must focus attention Duplex cold wall pipe installation the vertical spacing of the rows and a tube, which is easily ignored items, but its stability associated with the use later. Third, check before ramming pressure test conditions should be installed at the gas steam boiler, must not be omitted in this step, the various temporary support removed, the furnace building to a detailed inspection if the conditions to meet the requirements, which during the installation process is very important, because the details leading to the boiler installation to avoid problems caused by follow-up questions. Described above it is to install several points gas steam boilers, the installation must guarantee security, and the installation environment is also very important, if the installation is not up to the environment, to improve the security environment by means of transformation or change the installation location. In addition, the installation of gas steam boiler, also have to consider maintenance problems later, to extend the life of the boiler gas.
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.
Henan Gas boiler tube phenomenon and treatment 1, Henan gas pipe explosion phenomenon: you can hear the sound of soda injection time (1) squib, severe obvious explosions. (2) becomes pressurized combustion furnace by the combustion pressure, and ejecting the smoke and steam from the oven door opening and large air leakage at the furnace walls. (3) water flow is not normal, greater than the steam flow. (4) Although the increase of water supply, but the water level is often difficult to maintain, and the steam pressure reduced. (5) The exhaust gas temperature decreases, the color of white smoke. (6) furnace temperature is lowered, and even fire. (7) draft fan load increased, the current increased. Bottom (8) Henan gas boiler water flows out, an increase in ash. 2, Henan gas boiler tube process: (1) tube burst leakage is not serious and can maintain the water level when the accident is not to expand, maintain the operation load can be reduced for a short time, and then start to be standby furnace shutdown. (2) cracking furnace tube can not maintain the level, should an emergency shutdown, the induced draft fan should stop, should continue to Henan Sheung Shui gas boiler, reducing the wall temperature, the accident will not re-expand. (3) as a result of water shortage in Henan gas boiler, wall overheating when burst pipes, should an emergency shutdown, and prohibited the boiler feed water, then should withdraw from the furnace over the fire as soon as possible, reducing the furnace temperature, reducing the degree of boiler overheating. (4) if several parallel for the steam boiler, a main steam pipe and the steam should be the parent partition tube boiler accident.
Water tube boiler advantages:
1. The cross section of the water tube boiler tube is smaller than the outside of the tube, so the steam flow rate is greatly increased, and the steam generated on the heated surface can be washed away, which increases the heat absorption rate of the pot water.
2. The diameter of the water tube boiler is small, and the pot water capacity is small. Once an accident occurs, the disaster is lighter.
3. The boiler steam water system is complex, the water circulation is good, the evaporation efficiency is high, and the thermal efficiency is high.
