steaming cylinder with steam generator
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.
How to choose energy saving gas heating boiler? Most of the field of construction, industrial, life needs to be heating boiler, then what the election or steam boiler hot water boiler heating? How much tonnage, how many? And how to make energy-efficient and environmentally friendly choice of boiler it? These issues will no doubt cause great distress to the customer, the following solve these problems, we can do a simple discussion, consider providing some feasible ideas. A. How to determine the tonnage and the number of boilers must first be calculated from the area of heating and domestic hot water heat demand of the total amount for this issue. Meanwhile, in the calculation of the process, also taking into account factors external architectural features heating areas, temperature characteristics, the peak water heating, etc., due to local conditions at the time. Then, after completing a comprehensive evaluation, will be able to consider the issue of tonnage and number of units furnace, then how should the election, which requires analysis to analyze the results of previous projects using features of the boiler, but also to figure out the actual boiler operating efficiency, as well as tonnage and heat supply matches demand real problem customer site. II. When selected gas heating boilers, steam boilers or hot water is selected by boiler application analysis of many companies, both on a simple comparison, you will find hot water boiler will be energy efficient than steam boiler, so if there are energy-saving project demand, suggested the use of hot water boiler. Of course, both need something like hot water and steam needs, you need to hotels, hospitals and other places to determine the actual situation. If the hot water heating system using a large amount of steam required is very small, it is recommended to configure another small steam boiler or steaming cylinder with steam generator outside of the hot water boiler to meet the needs of a small amount of steam. For example, hospital star hotel or on the amount of steam demand does not exceed 30% of total heat demand, and based on actual experience, in addition to a steam boiler efficiency problem in itself a significant attenuation in the low load operation outside the state, the system energy loss larger, final energy efficiency is generally only about 60%, serious waste of energy. III. How to select energy saving gas heating boiler from the heat required systems, combustion systems, control systems and other consideration, and that is in heat transfer systems, taking into account the use of materials heat exchanger, steel, copper or iron, which according to their comparative property, currently used is copper; combustion system is the key to deciding whether the boiler equipment, energy saving and environmental protection. Current common combustion are: full-premixed, atmospheric premixed and diffusion. But just in terms of energy savings, premix technology would be more advantageous, it pre-mixed air and gas, multi-mode radiator heat, the intensity of the heat transfer improved. The advantage of using this method is that the combustion flame combustion clearer, and higher thermal efficiency. In short, the selection of gas heating boiler is a more complex issue, it requires theoretical and practical circumstances combined into consideration before they can get a reasonable result.
Power generation (MW) = boiler capacity × enthalpy content of the steam × steam turbine efficiency × generator efficiency
Electric heating steam boiler can be placed directly in the workshop steam from a steam boiler which is heated electrically to a point, then steam plant, that is, becomes condensate. Particularly to night non-continuous steam plant, each time before using the steam that is discharged will require large amounts of condensate, this time, that means the waste of energy. Then, it is on will be more in the management of personnel, need to be arranged over the holder Boilermakers were on duty, this way, that will increase the cost of the manual. To highlight the advantages of the now traditional electric heating steam boiler steam boiler, the first point is concerned, it is more to save energy, because eliminate the loss on the transport network, which is the way of saving energy will supply steam than conventional 30 -50%, so in terms of the case, which is able to meet the requirements of sustainable development. It is to pay attention to will be relatively simple in management, on the steaming cylinder with steam generator electric heating steam boiler that is, would not fall within the scope of the pressure on the boiler, this time, that can be placed directly on the shop inside, not We need to use a separate boiler room building. When needed direct steam plant workers on the steam boiler is heated by electricity will also be turned on, and the factory will be more beautiful.
