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.
What are the procedures required boiler chemical transformation procedures which transform chemical plant boiler needs? Legitimate boiler heating units must have five certificates. First filed by the heating unit to the heating sector, and then jointly reviewed by the environmental protection department, planning department, quality supervision department, fire department and office heating. Boiler room can only be completed after the approval, licenses can only be issued after a warm license acceptance. Only after the approval of the license by the heating, the price department to apply for a license fee. What approval process transformation unit boiler needs? The transformation of a chemical plant boiler is divided into two parts, one boiler, this part of the transformation of approval is very troublesome. First of all have qualified designing institutions of rehabilitation programs, and then to the local Bureau of Technical Supervision approval. Then to the boiler inspection office record, ready to check. After the completion of these formalities, it must be handled by qualified construction units, after construction is completed, the boiler inspection by the inspection agency. Another part of the transformation does not require any approval that the furnace section, does not move as long as the pressure part of the boiler, furnace walls, arches, steel and other random changes, without supervision and inspection.
No matter what type of pressure hot water boiler, furnace pressure hot water are always consistent with the atmospheric pressure, the water temperature will not change with the change; the contrary, the pressure of the boiler furnace because of its soft drinks from the closed system vessels and piping components, the furnace pressure is higher than the outside atmospheric pressure, the water temperature will also rise faster. Second, look at the professional level control problems because the supply pressure hot water boiler is not operating pressure, the pressure in order to achieve operation of the boiler circulating pump inlet and the outlet is connected to suction hot water in the heating boiler to a user, user return pipe connected to the water inlet of the boiler, the water is equal to the amount of water. Thus, pressure hot water boiler water level control in question, still connected to the top of the box in the opening drum full of water. The pressure hot water boiler water level control is no problem, which is one of two significant differences. Third, look at the structure of constraints pressure hot water boiler on the structural parameters of the issue, compared with pressure hot water boiler much simpler. Unlike the structure of the pressure in the boiler strictly limited boiler capacity, parameters, mounting position, etc., only reasonable pressure hot water boiler heating surface arrangement, water circulation to ensure reliable basis, little limitation on the structure, may be large degree design, construction and installation according to actual needs of users, more flexible and convenient. This is the pressure hot water boiler then more and more important reason for the user's favorite move.
What are the similarities and differences of the transformation of the former coal-fired boilers and gas boilers after the transformation? Gas boiler coal-fired boiler is new energy in the transformation of the current common form of transformation of the way, then the gas boiler after the transformation of the former coal-fired boilers and transform what difference does it make? 1 relative to the coal-fired boiler gas boiler is required in terms of pipeline, the storage device does not require the fuel, which saves a lot of transportation and storage costs. 2. Limitations of coal-fired boiler itself, cinder dust and so need to be addressed, while coal-fired boilers do not. 3. Clean gas boiler belong to the nature of the energy in the auxiliary equipment will save more necessary auxiliary equipment, such as dust category, soot-blowing class and so on, it would also save a lot of extra power loss. 4. A gas boiler as the boiler clean energy, pollution, is not conducive to wear problems and less parity boiler, so that smoke can use high-speed, reduce the area of the convection heating surface, then the heat energy of the flue gases will take a certain amount of reducing the thermal efficiency of boiler operation will be relatively high. And these are coal-fired boilers unattainable. Through the above analysis, we can also see the need for a gas coal-fired boilers, coal-fired boiler or change the new energy boiler is relatively large, on the one hand a certain extent, energy savings, lower emissions, on the other hand, the long-term significance on consideration, with the integration of new technologies can also save some input costs.
