oil fired vertical hot water boiler for school
(Iii) use of a waste heat boiler for heat recovery. Using the waste heat boiler using waste heat discharged from the heat of the flue gas in a boiler to heat water or generate steam. Such waste heat boiler is provided thermal oil furnace itself does not change the fuel consumption, the waste heat boiler to produce steam or hot water may be used for the production and the occurrence of heating, thereby indirectly ADSF fuel savings. A waste heat boiler provided the following effects: First, since the heat recovery water, it is easy to improve the thermal efficiency of the furnace. Second, because the number of boiler flue gas can be centralized heat recovery, thereby reducing the cost of construction of the heat recovery unit.
Hebei province is the use of industrial boilers, countless large and small boilers, air pollution caused by coal-fired boiler is one of the problems of governance in Hebei Province, and therefore become a major coal-fired boiler control of air pollution in Hebei Province direction. Coal-fired auxiliary boiler control work steadily, the Hebei provincial government to develop a "" comprehensive management of air pollution in Hebei provincial financial assistance fund management approach ", the boiler subsidy detailed as follows:
1, rural areas electricity instead of coal subsidies
The household equipment purchase and install (including line transformation indoor) 85% of investment subsidies, the maximum subsidy per household amount not more than 7400 yuan, the provincial and city and county respectively 50%, the rest borne by the users themselves.
Residents give electricity for heating 0.2 yuan / kwh subsidies, provincial, city and county average bear, the highest household electricity 10,000 kwh subsidies, subsidies and standards tentatively scheduled for three years.
2, substitution of gas for coal in rural areas subsidy standards
The household gas equipment purchase and install the 70% investment subsidies, the maximum subsidy per household amount not more than 2700 yuan. Provincial cities and counties and respectively 50%, the rest borne by the user.
Heating gas for customers who use 1 yuan / cubic meter of subsidy per household per year up to 1200 m3 gas subsidies, provincial, city and county average bear, subsidies and standards tentative three years.
Given the highest building in the village of pipelines family home investment subsidies of 4,000 yuan, 1000 yuan assume the provincial, city and county to bear 3,000.
3, coal-fired boiler subsidy governance standards
Subsidies for coal-fired boilers, eliminate subsidies, a separate ban demolition of 30,000 yuan / tons of steam, the implementation of clean energy transformation of 80,000 yuan / tons of steam.
4, thermal power shutting down out of subsidies
Provincial for shutting down the unit by 300 yuan / kilowatt award given up, have been included in the national "Thirteen Five." Plan for shutting down the unit, illegal construction unit, run-of-life choice except unit and power capacity index trading.
1, Safety Precautions: 1 gas fired vertical hot water boiler for school room should comply with fire safety requirements, and equipped with the necessary fire-fighting equipment. Storage of flammable materials, such as oil, wood and the like. Non-smoking room, non-smoking room, non-idle personnel and miscellaneous personnel. 2. The operator should be familiar with the structure and performance of hot water boiler components, specifically the installation location and function of the main components, prohibit untrained personnel into the boiler room operation device. 3. A gas water heater enters the room the operator must carry combustible gas, before closing and power, gas chamber must be checked to ensure that the concentration of the gas chamber is not higher than 0.5%, is prohibited switch off transmission. At the same time, we must take effective measures (open windows and doors) for ventilation. 4. Before starting, the supply voltage must check meet the requirements, no phase ground fault or damage, electrical control equipment and mechanical devices meet standard requirements, trouble-free start. 5. Before you start circulating pump must ensure that the system of heat and hot water valve intact, hoist flexible, good pressure gauges, thermometers and other facilities, piping systems leak, the water supply tank water level to the required standard. Otherwise forbidden to open the device. 6. Before starting, you must check the gas supply system to ensure no leakage, pressure is normal, compliance (> 8KPa). If the air pressure is abnormal, the ban starts.
After the chemical plant boiler installation inspection What: What are the chemical plant boiler installation inspection and risk prevention measures after inspection of chemical plant boiler installation there is worth in-depth inquiry, as this real impact on the quality of the boiler installation, while for people's personal safety and the development of the industry have a certain influence. Only in-depth exploration stage after inspection of industrial boiler installation, in order to understand where the test content and methods to fully play the role of these test methods, and the timely detection of hidden dangers, do preventive work. To clean up, while regulating their own operation behavior. After the chemical plant boiler installation inspection of the basic content of 1, test environment and ensure the safety of operations. It is well known in industrial boiler construction process plays an important role, is an integral part of one of the devices, it is necessary to strengthen the quality inspection for the boiler, in particular post-installation testing more critical. Therefore, the basic content of inspection it is necessary to conduct in-depth analysis. First, check to ensure replacement parts. 2, the overall test of the pot. After checking for the environment and the safety of the operation, we should consider checking the overall quality of the boiler inspection. Checks the contents of this section, the main seams comprising the drum, the interface and the gas tube boiler, the liquid leaks and the like. In addition, the bottom of the boiler, also have in-depth and detailed examination to ensure that the overall quality of clearance. 3, test water quality management and water treatment equipment. Test water quality management and water treatment equipment is also crucial part, this is an important test session, because if this part of the problem, most likely boiler erosion occurs, so that the life of the boiler equipment decreased, this is not conducive to the smooth development of production work, it will also affect the actual benefits. Therefore, for this part of the examination will do the painstaking, careful, in particular, to strengthen the sampling and testing for water quality, see if it meets the relevant requirements. 4, testing for chemical plant boiler annex. Fan, oil level indicator, pressure gauge, thermometer, locks and other equipment. Boiler accessories. For these boiler accessories require regular inspection and examination, at the time of inspection should pay attention to these accessories and the device is fully functional. 5, test for the chemical dust and smoke desulfurization apparatus boiler. In order to promote environmental protection, industrial flue gas to reduce pollution and waste on the environment, the country has long been on flue gas emissions and wastewater imposes strict requirements. Thus, in the conventional detection boiler, flue gas desulfurization and dust removal means for detecting is essential.
