Small oil-fired boiler flameout protection device use: small oil-fired boiler furnace space Product Introduction small oil-fired boiler of large and adaptable load capacity. Rational design of steam separator apparatus built to meet user requirements need to use higher quality steam. Furnace open manhole, head holes, hand holes, to facilitate the internal furnace to clean up, make repairs, maintenance is very convenient. Boiler safety interlock with multi-level protection: protection pressure switch (higher than the set auto stop and pressure), the low water level protection (boiler water level is below the warning level in the body, and automatically cut off power alarm), the protection valve (boiler pressure exceeds the pressure of work, discouraged automatic blood pressure), ensure that the boiler in a variety of conditions foolproof, secure home. Mechatronics combined organic appearance, new sophisticated, compact, less space, easy to transport and install. Thermal insulation materials and the use of new high-quality white color plate package, lighter in weight, good insulation properties, beautiful, not rust. Use flameout protection device for small oil-fired boiler to prevent furnace explosion, the fuel (gas) boiler must be set flameout protection means functions combustion in the monitoring of the furnace (including an ignition when the ignition failure or combustion halfway off, typically 5 seconds the re-ignition, run 1 second, off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds after purging, and various auxiliary blowers automatically cut off power, the boiler stop running.) by the flame monitoring and control device component. Role is to monitor the flame control device signals the presence of a flame or interrupted. The main use of the photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an infrared type or ultraviolet type, A photoelectric conversion element, the working principle of the light converted to the corresponding strength of the radiation intensity of current. And a linear output state, sometimes weak induction current, through amplification, in order to have an effect on the controller.
It is well known that the petroleum and petrochemical industry is inseparable from the use of large-scale steam boilers for thermal energy conversion or filtration use. The reason why steam-type boilers will be selected for processing use. Because not only high thermal energy but also energy-saving and environmental protection can meet the needs of petroleum and petrochemical industry. Professional steam boiler can not only help the petrochemical industry to process smoothly, but also help enterprises to produce huge economic benefits to improve the production of petroleum processing. Let's follow the editor to see why steam boilers are used in the oil industry:
1, it can save processing costs more effectively because steam boilers can save energy and environmental protection in the process of processing and use to reduce power consumption, so the use of the corresponding in the petroleum and petrochemical industry can reduce the larger cost investment. Moreover, steam boilers use electric energy to process and use, so they can effectively save a lot of energy consumption and help enterprises reduce costs. Reducing the cost can be more beneficial to the petrochemical industry to use a large number of processing to improve economic efficiency.
2, the reason why steam boilers are selected for long-term processing and use in the oil industry with high safety and stability of steam pressure is also because steam boilers are stable in operation and can carry out effective range control. Moreover, the boiler can control itself in the safe operation of steam pressure value, and ensure the safety and stability of the equipment in the process of operation. Therefore, it is especially suitable for petroleum and petrochemical industry with large processing capacity and long duration.
3, boiler energy-saving technology highlights that petroleum needs the conversion of boiler thermal energy in the refining and chemical process to carry out normally, and steam boiler has unique energy-saving technology and can automatically feed water through frequency conversion technology. Moreover, the steam temperature and pressure can be automatically adjusted under stable conditions, so it can be more energy-saving and stable compared with the continuous working process, and it can also save energy and reduce emissions while ensuring the normal supply of petroleum processing at the same time.
In Harbin fifth session of the Fourth Session of the National People's Congress, coal-fired boilers governance as a key task to be mentioned again. Meeting specific targets: by 2019, Harbin will govern coal-fired boilers, boiler out of 35 tons and below do not have to upgrade conditions, starting 65 tons or more of coal-fired boilers and energy-saving ultra-low emissions transformation.
2019, Harbin will continue to strictly control the total amount and quality of coal, according to local conditions to solve the shanty towns, suburban town (township) village coal powder burning problem by briquetting, Burying to field, the way raw material cogeneration, effective path to explore the comprehensive utilization of straw, the straw open-air Jinshao continue to focus on the work to implement the required emission limits industrial emissions, car exhaust strengthen, kitchen fumes, dust and other site management, effectively improve air quality.
2018, Harbin City, air pollution, elimination of coal-fired boilers 1191 units, biomass boilers to replace more than 10,000 units, updated bi-fuel taxi 1270 units, 1323 units of new energy buses, comprehensive utilization of straw and prohibiting open-air work strength forward, ambient air quality fine days up to 312 days, an increase of 42 days over the previous year, the highest level since the ultra-high PM2.5 monitoring.
Increase productivity boiler system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.Free Chat
