The transformation of low nitrogen boiler as well as fundamental for many businesses to transform and upgrade the all-round production principles, then after the completion of the transformation of enterprises also need professionals to provide technical guidance and protection of services, the transformation of low nitrogen boiler optional companies must have perfect service system to fly as a guarantee.
How to effectively reduce the degree of corrosion of hot water boilers used boiler users know, a long time hot water boiler, it will produce corrosion conditions, which had a great impact on the life of the boiler. So how can we reduce the degree of corrosion of hot water boiler of it? The following describes the hope that everyone has to help. 1, the installation is arranged in the exhaust system of exhaust hot water boiler, a hot water boiler beneficial to exclude air and hot water system precipitates from the water by heating the gas, so that oxygen reduces corrosion. 2, water supply oxygen: when the hot water boiler is greater than 4.2MW rated power, the water should be oxygen; water boiler rated power of less than 4.2 should be oxygen. 3, controlling the PH value of the hot water boiler: the hot water boiler furnace PH is controlled between 10 to 12 so that it can form a protective film on the surface of the metal, to avoid the occurrence of oxygen corrosion. Corrosion great threat to the safe operation of the hot water boiler, and even affect the length of life of the boiler. Prevention hot water boiler heating surface corrosion and increase the length of time such as the use of boiler, the boiler management has become an important aspect. With the above measures oxygen corrosion problems can occur for hot water boiler heating surface play an effective prevention and mitigation, in order to ensure the safe operation of the boiler.
PLC programmable controller boiler system design autonomous, more laminated to the dynamic changes of the boiler, the boiler checked by running a real-time dynamic monitoring boiler pressure, level, temperature, long-term security to maintain the boiler.
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.
