Medical factors affecting the thermal efficiency of the perpormence test runof sawdust afbc boiler asper is8753 What? Medical factors affecting the thermal efficiency of the boiler What? Factors affecting the thermal efficiency of medical boiler What? Medical boiler during operation in addition to considering the stability and safety of boiler operation, but also need to take into account the point is that the thermal efficiency of the boiler operation, medical Under normal circumstances boiler mostly steam boiler, the factors affecting the thermal efficiency of the steam boiler What? (1) the exhaust gas temperature, in general, higher exhaust gas temperature of the boiler, it will take away part of the heat, causing heat loss. (2) the oxygen content of the oxygen content in the furnace is too small, it will cause incomplete combustion of fuel, resulting in reduced thermal efficiency and so on, similarly, the oxygen content is too large, the heat loss will result. (3) boiler insulation effect is general, poor boiler insulation material or insulation effect is not good, can cause rapid loss of heat boiler, it will also affect the thermal efficiency of the boiler. Arrangement (4) is generally pipe, if the pipe and valve unnecessary bends in the pipeline will have a resistance material advantageously run, this will also affect the thermal efficiency of the boiler. Of course, factors affecting the thermal efficiency of the boiler medicine there will be other factors, but above several common, will be briefly described, by understanding these factors, we also need to select the boiler making, in particular, to note that these overhaul point.
Steam pressure protection of steam perpormence test runof sawdust afbc boiler asper is8753 when the boiler pressure exceeds the rated value, the chain protection should be carried out: the method is to stop the furnace and stop the work of the combustion system; Can also change the burner, single-or double-stage combustion, but also can adjust the fuel, thereby reducing pressure, ensuring safe operation of the boiler. The pressure protection of the fuel (gas) steam boiler is the same as that of the water level, which adopts multiple protection: The pressure controller usually uses two pressure controllers to convert the pressure signal into the electrical signal. Its function is to transmit the different signals of high pressure and low pressure to the electrical switch, which can automatically control or interlock the external circuit.
According to Anhui Province to work in the 2018 year-end summary of the province, in 2018, Anhui Province, built-up area exceeding 35 cities steam tons / hour or less industrial coal-fired perpormence test runof sawdust afbc boiler asper is8753s as well as glass, ceramic industry, industrial kilns clean energy alternative to work. Complete 97 sets of clean energy alternatives, completion rate of 76.4%, exceeding the annual target of 50% substitution tasks.
It is reported that Anhui start from the following aspects to strengthen the control and management of coal-fired boilers, is over-done.
First, strengthen research, Mozhun the truth.
1, carry out key research, went to Hefei, Bengbu, Chuzhou development of industrial coal-fired boilers, kilns clean energy alternative research work, the front line, replace understand the business progress, issues and rationalization proposals exist.
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.
Gas-fired perpormence test runof sawdust afbc boiler asper is8753 facilities Description and types of noise: gas boiler in the boiler, which is typically what facilities there? And, in the course of its operation, which will produce noise? These two issues about gas boilers, but also we are more concerned about and want to know, so below, to explain in detail, and give the correct answer, so, in order to have a comprehensive understanding and correct understanding. Facilities 1. The gas boiler in the gas boiler, its facilities, mainly are: climate compensation system: When the ambient temperature is relatively high, it is possible to automatically reduce the water temperature of the boiler, to avoid problems. Economizer: Also called the condenser is primarily used to play the role of condensation and the like. Burner Regulator: below 5 tons for boilers, typically employ two-stage fire, while more than 6 tons, is the use of proportional control of combustion, in addition, for small burners, the combustion is mostly proportional control. Heat exchanger: Use it, you can effectively reduce the number of heat exchangers, thereby to improve the efficiency of the boiler room.
