Detailed knowledge of oil-fired boilers: Oil-fired Boiler (an oil-burning boiler) is a fuel-fired boiler, including diesel oil, waste oil and other oil boilers. The overall arrangement of the oil-fired boiler is similar to that of the coal-fired boiler, except that the bottom of the furnace of the oil-fired boiler is mostly made into the bottom of the insulation furnace with a tilt to the back wall of 10 °~ 30 °, in order to obtain good combustion characteristics. In order to atomize fuel oil, there are two types of fuel burner nozzle: mechanical centrifugal injector and steam atomized Y type injector.
Condensing boilers can be used in enterprises, hotels, military, railway stations, airports, factories, hospitals, schools and other occasions. Its main use features are: high thermal efficiency - more money; exhaust gas temperature is low - more environmentally friendly; output medium temperature - good steam / hot water quality; high safety factor - once an exception occurs immediately start the alarm system.
How much is the cost of the transformation of industrial boilers, industrial boilers transformation costs how much money? With increasingly stringent environmental policy, a lot of coal-fired boilers are in need of rehabilitation. For the cost of the required current business situation will have to see the boiler, if time is too long, then it has no value transformation, and not as a direct boiler for a new one for direct production. With more and more serious air pollution, people's environmental awareness is gradually increased, the country has issued a series of policies to combat air pollutant emissions, on the industrial boiler industry, small coal-fired boiler flue gas emissions contained in the dust, sulfur and nitrogen oxides can cause serious pollution of the atmosphere. Therefore, the coal-fired boiler to gas boiler has become a way now widely used. How much is the cost of the transformation of industrial boilers, to be determined according to need of rehabilitation component, location, and so on. In general, industrial boilers convert almost need to start from the following aspects: 1, removal of former industrial boiler auxiliary equipment; 2. Calculated by the heat transfer in the furnace, the furnace geometry is determined, the center position of the flame furnace, the furnace is re-injected, and after the original arch tube is made on the basis of the original slope. 3, installation of blast doors; 4. industrial boiler equipment 1.5 times the working pressure of the hydraulic tests carried out. Under normal circumstances, the pressure component of the boiler furnace should not be changed as much as possible, and only furnaces and furnace wall arch reform should be carried out locally.
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.
