It is quick to understand our side of the boiler, boiler and industrial furnace is Haimen sulfur dioxide, one of the important sources of emissions of nitrogen oxides and soot, boiler and industrial furnace to carry out remediation is to control total energy consumption, air pollution control, energy conservation an important measure low-carbon development.
Recently, Haimen government issued the "2019 Haimen boiler and industrial furnace remediation work plan" put forward requirements on the city's boiler and industrial furnace remediation work.
First, the target for the full year to complete the remediation boiler remediation tasks. DiBiao transformation of ultra-low emissions before the end of the year, the city's 2 sets of 35 tons of steam / hour or phase-out coal-fired boilers clean energy alternative to complete 2 sets of 75 tons of steam / h coal-fired boiler and 1 biomass boiler, completed 6 low nitrogen gas-fired combustion units transformation. Phase out coal-fired boilers to consolidate existing achievements regulation to prevent 20 tons of steam / hour resurgence of small coal-fired boilers.
Second, accelerate industrial furnace remediation. This year, the city's 32 industrial furnaces in accordance with the "out of a group, instead of a number, a number of governance" principle fully complete the comprehensive remediation tasks, promote the upgrading of industrial furnace and pollution reduction. And products of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln) and the like, according to cut-off high-pollution fuel combustion zone management requirements, the use of clean energy and heat plants, district heating Alternatively heat or the like.
Scheme requires 20 December, the district town organize and complete acceptance of the unit boiler and industrial furnace remediation tasks. Boilers have been removed embodiment physical treatment, use can not be recovered; coal-fired boilers use gas, electricity, light oil clean energy and stable operation of a month or more. Gas-fired low-NOx combustion transformation, the transformation of ultra low emission biomass boilers and coal-fired power boiler ultra-low emission transformation, to have construction contracts and construction unit transformation, after the completion of the transformation have qualified environment monitoring report. After the renovation of industrial furnaces to natural gas, electricity, light oil clean energy, the furnace can not be used and the coal and its products. Boiler and industrial furnace remediation in line with production safety regulations.
Chemical plant boiler energy saving measures which energy saving measures chemical plant boiler What? Industrial boilers in rapid development after the founding of New China, widely used in industry. Professional cycle plant can achieve industrial boilers transferring thermal energy, the temperature is maximized to facilitate efficient power generation or gas. Has been increasingly in the production and use of industrial boilers in our country, self-reliant self-marketing model for China's industrial development also offers a number of facilities. Energy saving measures which have a chemical plant boiler, the fuel adding fuel economizer energy internal molecular structure of various processing compound vary, the distance between the molecules and the molecule reduces the viscosity of the fuel increases, thus before complete combustion maximize atomization and refined. Can maximize combustion burning material inside the environment can be reduced by reducing the temperature of the flue absorb heat from the flue. Then add industrial boiler economizer can eliminate and prevent secondary coking tar burning oil, in order to avoid insufficient combustion furnace wall phenomenon, can achieve efficient energy saving and environmental effects. Second, add condensing economizer boiler exhaust industry there will be some water vapor. They can be widely used. Energy savings by addition condensation may take advantage of them. Condenser industrial boilers can be installed in the flue gas boiler. It can effectively recover energy efficiently in the flue gas to reduce the loss of fuel and flue gas compounds by condensation of water vapor and the absorbent. Reduce pollution emissions with high environmental awareness. Third, industrial waste heat recovery boiler high temperature exhaust gas, water vapor in the flue gas heat is always in a state, will not condense into liquid flows. By waste heat recovery apparatus, and can be collected in the collecting portion of the heat of the flue, for reuse. Maximum use of energy. Regenerative fuel may be by recovering waste heat, greatly improving the thermal efficiency of the conversion.
Electric steam boiler flue of accumulating a certain amount of soot how to deal with? Electric steam boiler furnace cleaning backpass long-term non-stop, accumulating a certain amount of soot or carbon black. Solution: When the temperature drops below the flue 50 ℃, check before entering the flue tail heating surface, and should completely remove the flue soot. If not burning, can be re-started ignition; if burning, should be replaced, repaired burning member; large negative pressure of the combustion chamber, so that gas will be no time to burn into the electric steam boiler tail. Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C and more stable during 1h openable inspection hole inspection, after checking element determines the source of fire, the ventilation fans before starting. When shutdown or electric steam boiler fire, air gun valve is not closed. Solution: strengthen the electric steam boiler feed water and turn on the water, open the valve or economizer recirculation tube to protect the economizer being burnt; lower start, the furnace temperature during shutdown, unburned fuel in the furnace . Solution: fire extinguishing devices immediately into steam, carbon dioxide or other fire extinguishing devices; burn improperly adjusted, with insufficient wind or with the wind unreasonable. Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan.
Steam boilers What is the function? Too many in the form of steam boilers, would like to give a quick four tons of ordinary steam boiler talk. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Let me say a boiler pot. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, through the grate in the rear portion of the olecranon iron discharged from the machine to send out of the furnace slag. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessels, safety devices is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used. Boiler water must be softened, as well as water treatment equipment.
