Chemical prevent high temperature corrosion of combined oil fired boilers supplier waterwall boiler chemical improvements to prevent high temperature corrosion improvements waterwall 1, using an anti-art windshear main principle is offset by a spray angle of air flow injection port, and the original jet forming a motion , the opposite direction of rotation, in tangentially running smaller diameter, due to the opposite running direction of the initial movement of the main gas flow direction of the gas flow in the furnace after the anti-wind shear, the pulverized coal injected hindered high-temperature air upstream of the primary air flow and the time, the pulverized coal injection speed is reduced rapidly, enhancing coal dead time in high temperature zone, to enhance the combustion efficiency of pulverized coal. By using an anti-wind shear can effectively prevent high temperature corrosion phenomena, and can enhance the ability to stabilize combustion in the boiler furnace, reduced coke boiler case, as shown in FIG. 2, using the technology of Side by side wind technology is mainly on the high temperature zone waterwall corrosion or high temperature corrosion installed upstream of the injection port area, and ejecting the air in the furnace boiler. Technology is mainly employed side air can be controlled in the high-temperature reducing gas corrosion area, enhanced oxygen content in a local range. 3, to improve the control operation to take excess air coefficient increases, a plurality of coal mills is not put into operation at the same time, reduce the coal particle size, increase the air preheater ash fouling preventing plugging of equipment and operation control systems such as high temperature measures to prevent High temperature corrosion phenomena.
To conscientiously implement the CPC Central Committee and State Council "on the overall strengthening of environmental protection and resolutely fight pollution prevention advice tough fight" and "the State Council on the issuance of three-year winning the Battle of the blue sky plan of action," the spirit, combined oil fired boilers supplier emissions control, prevention and treatment air pollution, the State environmental Protection Department to develop "boiler air pollutant emission standards." In order to further the implementation of air pollution control operations, all regions at the same time meet the national standard, but also have introduced a more stringent local standards.
From the implementation of the Beijing gas nitrogen oxide emission standards for boilers began 30mg, emissions from gas-fired boiler has been of great concern, expand around the "coal to gas" action, so that gas such devices become the most countries to promote clean energy boiler.
The transformation of the current common low nitrogen boiler, there are three main measures: (1) replacement of boilers, (2) replace the burner (3) in the boiler flue gas treatment.
Controlling the nitrogen oxide generated from the source, the most advanced technology on the market today is the use of flue gas recirculation techniques and FGR premix combustion gas boiler technology, both having different focus, low nitrogen emissions boiler.
Replace the boiler burner, renovation and debugging, and the impact on the safety performance of the resulting boiler, burner unit by the responsible manufacturer or his authorized. Beijing Bureau of Quality and Technical Supervision, Beijing Municipal Environmental Protection Bureau issued the "Notice on the transformation of the low - NOx combustion safety risk warning" states: the transformation of low-nitrogen combustion boiler diverse, complex technology, to protect the smooth implementation of the work of reform, effective prevent security risks, prevent accidents, analysis and appraisal by experts, it is not recommended comprehensive safety, environmental factors, the following recommendations:
Nitrogen oxides have been generated by some means and then reduced to nitrogen, the main fuel reburning, selective catalytic reduction, selective non-catalytic reduction. But in the actual monitoring, the nitrogen oxide emissions controllability is poor.
The transformation of low nitrogen gas boiler is a need for long-term adherence and actively manage the work, under the premise to meet the national standards, do specifically address the specific circumstances, not blindly, careless handling, to adopt plans, goals, ideas implementation, to achieve a comprehensive upgrade gas boiler.
Chemical plant four tons electric combined oil fired boilers supplier price is how much chemical plant four tons of steam electric boiler steam price is how much? Now, with the increasingly more stringent environmental requirements, many companies are using natural gas boiler, but there are places, not very rich natural gas resources, therefore, only electric heating boiler. Electric heating boiler with the most current output is steam. Recently there Chemical Consulting 4 tons electric boiler steam price is. For four tons electric steam boiler prices, the market there is still a great distinction between intervals, can differ by tens of thousands, for businesses, do not blindly choose low-priced products, this is the case, the latter is very troublesome. Electric steam boilers currently fast boiler 4 tons of around 360,000. For businesses, choose a bad boiler manufacturers, although the low cost pre. But time later use of the boiler, the cost of maintenance of the latter is very high.
If natural gas as combined oil fired boilers supplier fuel choice, because the convenience of clean natural gas and fuel used in the boiler service life will be over 10 years; but if it is a boiler coal or other fuels, it will shorten the life of some. Further, the life of the boiler with the use of the frequency, the higher the frequency the shorter the life of the boiler, the greater the contrary. Late boiler maintenance is also very important for the life of the boiler, good maintenance will extend the life of the boiler.Free Chat
