7 ton steam boiler in building materials industry
Handan: Before the end of October to complete the transformation of more than 10 tons of steam gas boiler burning low nitrogen
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.
Coal-fired industrial boilers need to pay attention to what the transformation of coal-fired industrial boilers need to pay attention to what 1, before removal of the original boiler transformation of the original boiler should be removal of the original main and auxiliary boilers, special demolition work carried out by professionals, so that the whole demolition work done faster to prevent accidents during the removal process. 2, note that the pressure of the boiler, the boiler combustion medium small conversion to gases, but also the original draft combustion into the combustion pressure. In this process, the user needs to pay particular attention to the structure of the whole furnace walls and seal. If the sealing performance is not good, can not withstand the pressure of the boiler, accidents will happen. 3, furnace conversion factor; in many cases the gas burner for the time, because the fuel atomization poor or incomplete combustion furnace gas surplus will be subject to any influence of fire or explosion caused by carelessness, so the transformation is complete should be appropriate where blast doors were installed to prevent the explosion, while increasing the ignition flameout protection device to ensure the safe operation of the boiler; 4, after the transformation test, the need for complex trials to determine the safety after the transformation of high-quality boiler sex. Common method of detection is the pressure after the high-pressure water boiler transformation test. Finally, only after the tests meet the standard, boiler to complete renovation work.
Run industrial boilers areas requiring attention are what run industrial boilers to note what? Mainly industrial boilers to provide heat and power for other industrial production equipment in order to maintain the momentum of its production and operation. One of which is industrial boilers, mainly to maintain the steam-powered electricity generation or supply. Another is the traditional industrial boilers, coal as raw material which, powered by waste heat recovery, to maintain production run, it is widely used in industrial production. 1. Use industrial boiler operators, requires not only the knowledge and skills of skilled operators, the operation of the boiler should be prohibited from leaving their jobs, the boiler in a state of neglect, reduce accidents too much pressure boiler water level or higher The phenomenon. 2. When the boiler pressure increases, the staff should be subject to rigorous technical evaluation of relevant professional departments to be adjusted to avoid overpressure phenomenon mislead operator error without adjustment. Pressure gauge and safety valve common faults, while related to the operation of the operator should be strengthened. Timely processing of boiler operation anomalies. 3. Prior to the use of the boiler, the boiler should be fully checked structure and current and voltage is within the normal range. To avoid unreasonable boiler structure, poor weld quality, safety accessories related failures caused by industrial accidents occurred in the boiler during operation, and should be sufficient for boiler water treatment prior to use to reduce the incidence of accidents in the run and run.
