condensing heat exchanger for boilers
Gas works gas steam condensing heat exchanger for boilers steam boiler is a very wide range of applications, for example in food processing, electronics industry, sauna bath, chemical industry, scientific experiments are inseparable from it, the same, it is also to promote economic an important factor in development. At the same time, but many of us do not know how he works. In fact, gas steam boiler works is very simple, it is the use of natural gas, LPG, city gas and other gases as fuel combustion in the furnace put out heat, which heats the water in the boiler, so that it vaporized into steam thermal energy conversion device. Water drum is continuously released from the combustion furnace gas heat energy to raise the temperature of the fuel and to generate steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the boiler steam drum is set at the saturation pressure and heated to vaporization of the water formed, is widely used as an energy source. Simply means that the natural gas through the combustion gas from the furnace heat absorption and heat transfer to the water in the furnace, the upper portion of the boiler and the air bag set has a steam generation process. The furnace wet back, waveform furnace structure, heating surface are arranged symmetrically, so that the force and expansion of the boiler is more reasonable to ensure good water circulation and heat exchanger, heat transfer to achieve the best state, to improve the thermal efficiency of the boiler. But also to avoid the back wall of the high temperature flue gas can damage the safe and reliable operation of the boiler. But also improve the life of the boiler. Gas-fired steam boiler not working principle is simple, reasonable structure, long life, but also an efficient and environmentally friendly products, which also and his works have a close relationship.
Which operating costs Food Factory Food Factory steam condensing heat exchanger for boilers steam boiler operating costs have what? Food factory, is the need to consider the cost of running the boiler, after all, spending in this area is great. Therefore, companies need to be accounted for costs in this regard. Because the boiler fuel costs can account for the total cost of running the boiler nearly 90%, other electricity boiler operation is put into the boiler (boiler and burner give (up) pump) lighting and electrical consumption, run-time power consumption), water consumption (water) boiler, labor costs (salaries), boiler maintenance costs. If food plants using natural gas-type gas boilers, steam boilers according to the required operating time per day every day the amount of steam and hot water boilers, above all converted to full-load operation time. Tonnage boiler unit with a gas (80 cubic meters per hour per ton of the boiler) and natural gas can be monovalent. 1 ton gas steam boiler, for example: (1) When the rated evaporation capacity of 1 ton / hour, fuel consumption is 70 cubic meters of natural gas, according to 3.5 yuan / cubic meter natural gas prices (around the price is not very different), natural gas cost of 70 to 3.5 million yuan to 245 yuan; (2) gas-fired boiler during normal use, power is 0.65 times, at full power, so the power capacity of the boiler (1.5kw + 2.2 kW 2 kW) * 0.65 = 3.7 kilowatt, if electricity is 1 yuan / kWh, the power boiler per hour 3.7kw * 1 = 3.7 yuan.
Coal Pulverisers grind the coal to a very fine powder to make it burn easily. Pulverisers have steel rollers or steel balls which crush the coal between them into a fine powder. This powder is easy to burn. Coal contains moisture. Hot air form the Primary Air Fans dry the coal in the pulverisers. This makes the burning easy and efficient. This air also carries the dry coal powder from the pulverisers to the burners in the condensing heat exchanger for boilers furnace.In the burners the coal powder is mixed with the required amount of Combustion air and burned in the furnace.
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.
