Boiler

Explain the structure principle of hot water boiler in detail

Hot-water boilers include electric hot-water boilers, oil-fired hot-water boilers, gas-fired hot-water boilers and coal-fired hot-water boilers, etc. Hot-water boilers are boilers that process hot water. A heating tool that uses heat released from fuel incineration or other heat to heat water to extra temperatures. In the natural circulation hot water boiler, the inlet and the outlet water are received on the top of the pot. It is the inlet line that leads the lower inlet pipe into the front and lower side of the header and heats up through the inlet cold wall tube. In front of the drum, there is a water barrier at the lower boundary between the lower and the forward water flow, and only the lower half of the drum is separated by the water insulation plate.

Recently, Anshun City, Guizhou Province, Anshun City, issued a notice to win the embodiment of the three-year action blue sky Battle, as follows.

First, the implementation of the total coal consumption control

Accelerate coal mergers and acquisitions, consolidation pace of technological transformation, and resolutely eliminate excess capacity to resolve the coal. Before the end of 2018 to complete the county level and above cities restrict coal-burning zone and the coal area delineation work to strengthen the loose coal burning and fireworks control, prohibit the sale, banned the use of coal, petroleum coke, high-polluting fuels. Vigorously implement the "coal to gas," "coal to electricity" project, increase the proportion of electricity, natural gas in energy consumption. By 2020, the city's coal accounts for the proportion of energy consumption is reduced to 70% or less.

Second, to carry out comprehensive improvement of coal-fired boilers

Before the end of 2018, the central city out of 20 tons of steam per hour of coal-fired boilers, 35 tons of steam per hour to start the following phase-out of coal-fired boilers. Atlantic Town Center City led Xixiu on the wind direction, seven Town, Cai town official reference implementation of February 15, 2015 promulgated the "Anshun City People's Government on delineation of high-pollution fuel combustion zone ban of" 3.5 Kunming Shanghai high speed range on both sides of one thousand meters anshun prohibit new paragraph 35 tons of steam coal-fired boilers. By 2020, the county (district) total phase-out urban area and 10 tons of steam coal-fired boilers, basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment. Center City ban on new built-up area per hour and 75 tons of steam coal-fired boilers, county (district) urban area 35 tons of steam per hour ban on new coal-fired boilers and other regions 10 tons of steam per hour ban on new coal-fired boilers . Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage.

Third, improve energy efficiency

Continue to implement the action of the total energy consumption dual control and strength. By 2020, the city's yuan GDP energy consumption fell 14% in the region, the total energy consumption control in less than 28.55 million tons of standard coal, new energy consumption control in less than 100 million tons of coal. Strengthen the implementation of energy efficiency standards to promote, develop, promote energy-saving technologies and products to achieve key energy industries, energy-saving equipment standard full coverage.

Fourth, accelerate the development of clean energy and new energy

As of 2020, the installed capacity of wind power reached 200,000 kilowatts; actively seek Zhenning County, Guanling County, Ziyun County PV poverty alleviation projects Indicators Program, to encourage qualified enterprises to implement photovoltaic bidding, led a group of farmers light, light forest project floor building.

How to treat boiler waste water

During the long-term operation of boiler, the water treatment equipment will inevitably aging. When the equipment is in abnormal operation, the pollution density of the water supply is larger, and there is a certain amount of sediment in the water supply process. When the water with sediment component evaporates in the boiler and more sediment materials are precipitated, the boiler pipe will be blocked, the heat dissipation effect will be poor, and the probability of tube burst will occur. The formation of boiler slag will clog the furnace tube and cause tube explosion if it is not discharged out of the furnace at regular intervals. At the same time, it also reduces the heat transfer effect.

Teach you how to select a 3 ton disinfection steam boilers heat exchangers: steam boiler heat exchanger is generally divided into two, one is in direct contact with a heat exchanger, and the other is an indirect heat exchanger, which are separate means is used to flue gas waste heat recovery, to achieve energy saving effect. Generally conventional steam boiler can be increased by a simple transformation of energy-saving effects, such as increasing the installed heat recovery unit, which is the energy-saving advantages of steam boilers. Energy savings from the big side, is to promote the cause of saving the country, to say that small ways to create more profits for the enterprise cost savings, choice of heat exchangers is one good way to achieve energy efficiency goals.
