2, a diagnostic investigation, issued "regarding the development of cities and built-up areas 35 steam tons / hour boiler and industrial enterprises and the glass and ceramics industry, industrial kilns investigation work" and collect aggregate and cross-checking data to improve municipalities investigation; Third, learn practice field, go to Tianjin, Hebei research study "coal clear" action and glass industry furnace clean energy alternative to work, learn from the successful experience of leading regions. Grasp the province's boiler, furnace conditions first-hand data, be aware of the difficulties of enterprises, clear focus and difficult work.
Second, a clear mandate to strengthen the scheduling.
Issued a "built-up area of Anhui Province cities 35 tons of steam per hour of coal-fired industrial boilers as well as glass, ceramics industry, clean energy alternative to coal-fired furnaces work plan", based on clear objectives, tasks, scope and duration of the transformation node, proposed work requirements. And issued a "35 tons of steam and industrial coal-fired boilers and the notification submitted on a regular basis municipalities built-up area per hour, glass, ceramics industry, coal-fired kilns clean energy alternative to progress information", and held a forum, a monthly tracking scheduling progress, and urge municipalities in accordance with the program of work, and steadily promote the implementation of alternative work schedule.
Third, innovative initiatives to promote accurate.
For enterprises in the implementation of coal-fired boilers, furnaces clean energy alternative technology transformation encountered financial problems, the implementation of precise advance.
1, the organization held a provincial industrial boilers clean energy alternative technical equipment special promotion, targeted Recommend energy-efficient air units, heat pumps integrated device source, environmentally friendly low-emission of nitrogen gas boiler and a number of boiler clean energy alternative to new technology and equipment, docking platform to build both supply and demand.
2, a clean energy alternative to key projects in 2019 included green manufacturing project-oriented investment program to enhance the enthusiasm of enterprise transformation.
1, gas steam boiler before ignition must conduct a comprehensive examination, including the burner and related accessories and pipes are complete good, the operation is flexible. Before the water is not required to close the drain valve, open a safety valve, allowing air furnace can be discharged. After all the examination was normal, boiler before ignition Sheung Shui, Sheung Shui to drum should be the normal water level, turn on any air, flue baffle. Start the blower, the flue of the furnace and vent purge, purge time is not less than 30 seconds, and then start the ignition burner.
2, the treated water injected into the gas boiler, the water temperature should not exceed 40 ℃, when the pot water level reaches the lowest level, i.e. the inlet valve closed, to observe whether the water level is lowered. After firing the pot should always pay attention to the water level, the water level will rise as a result of exceeding the maximum safe water level can be heated sewage.

Heat Transfer by Convection (Hot Water and Oil) In contrast, hot water and oil transfer heat by convective heating, which does not involve a change of state. If left to natural convection, heat transfer is extremely slow. Thus, a pump is typically used to create flow against the heat transfer surface to increase the rate of heat transfer.
