combi hot water boiler for industry
1, boiler flue gas condensate two main reasons
(1) to condense water vapor in flue gas at a temperature below the dew point;
Recently, Anshun City, Guizhou Province, Anshun City, issued a notice to win the embodiment of the three-year action blue sky Battle, as follows.
First, the implementation of the total coal consumption control
Accelerate coal mergers and acquisitions, consolidation pace of technological transformation, and resolutely eliminate excess capacity to resolve the coal. Before the end of 2018 to complete the county level and above cities restrict coal-burning zone and the coal area delineation work to strengthen the loose coal burning and fireworks control, prohibit the sale, banned the use of coal, petroleum coke, high-polluting fuels. Vigorously implement the "coal to gas," "coal to electricity" project, increase the proportion of electricity, natural gas in energy consumption. By 2020, the city's coal accounts for the proportion of energy consumption is reduced to 70% or less.
Second, to carry out comprehensive improvement of coal-fired boilers
Before the end of 2018, the central city out of 20 tons of steam per hour of coal-fired boilers, 35 tons of steam per hour to start the following phase-out of coal-fired boilers. Atlantic Town Center City led Xixiu on the wind direction, seven Town, Cai town official reference implementation of February 15, 2015 promulgated the "Anshun City People's Government on delineation of high-pollution fuel combustion zone ban of" 3.5 Kunming Shanghai high speed range on both sides of one thousand meters anshun prohibit new paragraph 35 tons of steam coal-fired boilers. By 2020, the county (district) total phase-out urban area and 10 tons of steam coal-fired boilers, basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment. Center City ban on new built-up area per hour and 75 tons of steam coal-fired boilers, county (district) urban area 35 tons of steam per hour ban on new coal-fired boilers and other regions 10 tons of steam per hour ban on new coal-fired boilers . Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage.
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.
Several characteristics of a gas steam boiler, steam boiler burner gas supplied by well-known manufacturers in the world, according to the automatic combustion controller instructions, stop, separate control box has a number of security, safety and stable performance, low maintenance. 2, advanced automatic steam boiler controller, Chinese LCD screen, the man-machine interface, the user simply easily set, i.e., according to user requirements boiler start and stop, load adjustment, automatic water supply, such as automatic operation. Boiler fully functional, complete protection, easy to operate, safe, reliable, self-diagnostic function. Boiler operation anomalies automatically interrupt burning, audible alarm once appeared. 3, vertical steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost. 4, horizontal steam boiler shell type three return all wet back downstream pyrotechnic tube structure, economy. Waveform threaded pipe and furnace structure and improve the strength of heat absorption of the boiler, the heating surface needs thermal expansion. 5, in strict accordance with the present boiler "Steam Boiler Safety Supervision", JB / T10094-2002 "industrial boilers general technical conditions", JB / T619-2002 "boiler manufacturing technology conditions potshell" requirements, design, manufacture, monitoring inspection to ensure good quality of boilers, achieve low energy consumption, high thermal efficiency, stable pressure, gas and quantity, economic use. 6, a large boiler furnace space, storage, steam and more 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. 7, is provided with a multi-stage boiler safety interlock protection: Pressure switch protection (higher than the set auto stop and pressure), low water protection (boiler water level is below the body of the warning level, the alarm and automatically cut off power), the protection valve (boiler pressure exceeds the pressure of work, discouraged automatic blood pressure) to ensure foolproof boiler in a variety of conditions, safe home. 8, the combined organic appearance of mechatronic, sophisticated new, compact, less space, easy to transport and install. 9, using the new material and the thermal insulation quality white color plate package, lighter in weight, good insulation properties, beautiful, not rust. 10, automatic / gas steam boiler is widely used in hospitals, schools, textile mills, garment factories, clothing stores, garment factories, dry cleaners, restaurants, hotels, bread stores, hotels, canteens, restaurants, food plants, beverage plants, soybean plants, meat plants, canneries, wineries, pharmaceutical, packaging factory, building materials factory, paint factory, beauty salons, bath, sauna, steam room, baby swimming pool and other enterprises place.
Boiler start and stop frequently to how to deal with? On-site operation of the boiler load is low, gas consumption Japanese unstable gas pressure controller hysteresis little contact or poor contact can cause the boiler start and stop frequently. If they are relevant, must be timely treatment: 1. site boiler operating load of not less than 30% of gas consumption 2. Adjust the steady pressure difference 3. Replace the back pressure controller Note: If you are not taking into account the load is too small to burn machine start and stop frequently, then, like the modulating burners machine, start and stop the burner may be adjusted by trimming and setting the PID parameter deviation.
