What differences have low nitrogen crude boiler refinery with ordinary boilers? We all know now the boiler furnace oil and gas market sell very popular, especially for low NOx combustion of furnace oil and gas is in short supply. However, for many boiler manufacturers, the low nitrogen technology is even more difficult to overcome the problem, the birth of low nitrogen boiler is a milestone, a professional low nitrogen furnace boiler developed by the company's low-NOx combustion technology has been widely used in the industrial boiler application. 1, since the difference in emission layer burning combustion mode, combustion chamber, different circulating fluidized bed boiler, the furnace in different structures, the original NOx emissions which there are large differences, in general, not specifically for low NOX combustion furnace technology employed when , circulating fluidized bed low NOx raw emissions, NOx emissions to the original furnace chain represented slightly lower layer burner, pulverized coal-fired boilers industrial boilers room, the higher the NOx emissions original, well-known low nitrogen emissions from boilers are but Greatly reduced. 2, the different layers combustion boiler technology, combustion chamber, circulating fluidized bed boiler may be different with different low NOx combustion technique in accordance with the combustion mode, the combustion boiler for the air distribution layers using an air classifier, and more often to achieve low nitrogen Gas Recirculation combustion; under typical flue gas recirculation layer influence combustion boiler combustion zone, in conjunction with the air fractionation techniques for reducing NOx by catalytic char; super reduction furnace denitration technology in recent years, new furnace denitration technology, by combustion reasonable location of the flame spray region ammonia, direct denitration at a high temperature flame. Low Nitrogen mainly the secondary air boiler, the coal to the location and distribution of optimal adjustment of the mouth, or the like to increase the flue gas recirculation system. 3, at different central security layer after combustion, combustion chamber, low-NOx combustion furnace circulating fluidized bed boiler technology a large number of tests performed, it has been verified in engineering applications, in general, a low nitrogen boiler to safety higher, the reason why in recent years, its sales volume increasing, there are many users because of its high security, a small threat to the space environment to buy, and this is one of its important differences with ordinary boilers.
Burner What are the main components of the crude boiler refinery burner, by definition, refers to the use of the burner on the boiler, boiler fuel gas-fired boiler burner is an important equipment. If the burner on strike, then the boiler will not burn up. Since the boiler burner is so important, we have to look at it part of it. See below: 1 air supply system. Function into the air supply system is to a certain wind speed and amount of air to the combustion chamber, its main components are: a housing, fan motors, fan impeller, air guns fire tube, damper controller, damper baffle, a cam adjustment mechanism, diffusion plate. 2. The ignition system. The function of the ignition system ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. Flame length, taper angle, the shape of the design according to user requirements. 3. Monitoring System. Function monitoring system is to ensure that the burner safe and stable operation, the main components are flame detectors, pressure monitors, temperature monitors and the like. 4. The fuel system. Function of the fuel system is to ensure that the desired fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The gas burner mainly a filter, pressure regulator, solenoid valve, and then firing solenoid valve, the fuel valve. The electronic control system. Electronic control system is the command center and the focal point for the above system, the main control element is a control box, for different burner with a different programmer, common control box has: LFL series, LAL series, LOA series, LGB series the main difference is the time of each different program steps.
A few days ago, Handan City issued "on the deadline to complete the nitrogen oxide gas boiler governance" (the "Notice"), clear objectives, tasks nitrogen oxides governance gas boiler, expected to be completed more than 10 steam tons of gas before the end of October this year, low NOx combustion boiler reconstruction. "Notice" to the objectives and tasks of nitrogen oxide gas boiler control, time requirements, safeguard measures have been clearly defined.
First, the implementation of the transformation of ultra-low emissions
By the end of June 2020, the existing non-electrical gas steam boiler, hot water boiler, Stoker stoker furnace and completed the transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxides reach 5mg / m³, 10mg / m³ , 30mg / m³, the new gas combustion boiler synchronizing means and is mounted low nitrogen meet emission standards. 20 tons of steam / hour or more gas-fired boiler installation atmospheric pollution automatic monitoring facilities, and networking with the environmental protection department, install a distributed control system (DCS system). 20 t steam / hour to be mounted gas-fired boiler exhaust gas nitrogen oxide analyzer.
Second, the phased completion of the task of transformation of governance
10 before the end 2018, to complete the combustion of the transformation Boilers nitrogen over 10 tons of steam, to complete the 1-10 tons of steam (having a steam tons and 10 tons of steam) combustion transform low nitrogen gas boiler before the end of October 2019, 2020 at the end of 6 before completing the transformation of low-nitrogen combustion gas steam boiler 1 ton. Counties (cities, districts) according to the actual situation, to be completed in advance of nitrogen oxides governance gas boiler.
Third, both subsidies and penalties
"Notice" requirement for acceptance of project management, to give appropriate subsidies comprehensive financial subsidies to control air pollution. Due to the unfinished task of governance be ordered to stop production of governance. For excessive emissions, fraud, unauthorized outage environmental protection facilities, waste-water treatment snuck issues such as rectification and punishment according to law; wrongdoing, be held criminally relevant personnel.
0.5 tons gas crude boiler refinery introduced: 0.5 tons of gas boiler Description: 0.5 tons of gas boiler imported burner, automatic programmed control, automatic purge blower, electronic auto-ignition, spontaneous combustion and gas, (air) automatically adjusting the ratio of wind oil good atomization, combustion, low NOX, energy saving and environmental protection. Under normal circumstances, when the boiler steam pressure reaches the set value, the burner combustion is automatically stopped, when the steam pressure is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically.Free Chat
