Third, improve energy efficiency
Continue to implement the action of the total energy consumption dual control and strength. By 2020, the city's yuan GDP energy consumption fell 14% in the region, the total energy consumption control in less than 28.55 million tons of standard coal, new energy consumption control in less than 100 million tons of coal. Strengthen the implementation of energy efficiency standards to promote, develop, promote energy-saving technologies and products to achieve key energy industries, energy-saving equipment standard full coverage.
Fourth, accelerate the development of clean energy and new energy
As of 2020, the installed capacity of wind power reached 200,000 kilowatts; actively seek Zhenning County, Guanling County, Ziyun County PV poverty alleviation projects Indicators Program, to encourage qualified enterprises to implement photovoltaic bidding, led a group of farmers light, light forest project floor building.
Electric boiler for sugar factory is an indispensable heating gas in winter, that is, the most important electric boiler is not suitable to place combustible materials (paper, cloth and other combustible materials) around the boiler, which can reduce the occurrence of fire from the source. 2. Electric heaters do not have plugs, plugs forget to be unplugged and resistive wires are overloaded, or aging plugs and cables can also cause fires. 3. When using electric heaters, people should always be kept on the edges, and power plugs should be unplugged when they are not in use. Many people do not have the habit of unplugging the switches, but this will also give a fire a chance of fuelling. 4. If there is a sudden power outage, Unplug the heater to prevent incoming calls A fire broke out with a sudden increase in electric current.
01. Thermal control system classification of fuel-fired gas-fired boiler (1) Electric instrument combination system mainly consists of relay, time relay, program relay and so on, which consists of program control and interlock protection system; The monitoring and regulating system is composed of electric unit combination instrument or digital and intelligent series instrument, measurement and display instrument, acousto-optic alarm instrument and so on. The design experience of electric instrument system is mature and the price is cheap, but it is difficult to realize the redundancy of the system, data transmission and maintenance, and it is also difficult to realize the advanced control method. The electric instrument system is mainly used in the small boiler, but the electric unit combination instrument is used in the closed loop adjustment. The use of cases has been reduced year by year, almost replaced by intelligent multi-functional instruments, The electrical unit assembly instruments mentioned in the following sections are simply intended to illustrate the principle and composition of the regulation system using a series of instruments familiar to the industry and widely used in that era. (2) the core of programmable control system is programmable controller (PLC). The programmable controller has been widely used in logic control at first, and the ability of process control has been increased since 1990s, which makes the application of programmable controller in the field of process control more and more extensive.
Gas-fired steam boiler for sugar factory safety valve from installation to use, it must remain vigilant safety valve is one of the most important components of the gas steam boilers, boiler probability of the risk occurring due to various incidents can effectively suppressed. This article focuses on the safety valve from installation to use several important considerations, we do not ignore the use of gas when it steam boiler. A Notes 1 safety valve, the safety valve should be mounted vertically in a high position in the pot business, set box. 2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. 4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm. 5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve. 6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. 7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. 8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve. 9, separable economizer outlet, the steam superheater outlet valve must be installed.
Method for safe operation of steam boiler for sugar factorys steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Refers to the operation of the steam boiler is refluxed pressure activated device circulating pump, the circulating pump outlet, inlet, outlet, and the system, it is in the normal range. Circulation pump run for 30 minutes. After the stability of the system, the next step. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, if you accidentally quenching phenomenon occurs, the device will automatically interlock burner saver appear. It must be promptly cut off the natural gas pipeline to start the furnace purification. Replacement of the residual gas in the furnace and closed.
