You must know the problems of energy consumption boiler (boiler thermal efficiency) 1, because the thermal efficiency of boiler problems of a high exhaust gas temperature. b sootblowers into low. c ash combustible large. d is too large or too small boiler oxygen. e heat loss is large. f large air preheater air leakage rate. g coarse pulverized coal. h steam - water quality is poor. I defective equipment, operating parameters are forced down. 2, measures to solve the problem of a lower exhaust gas temperature. b timely elimination of soot blowers defects and improve the investment rate of soot blowers. c reduce fuel ash, slag combustibles. d control the amount of oxygen in the boiler. e reduce heat loss. f air preheater to reduce air leakage rate. g qualified coal fineness control. h to improve the quality of soft drinks. i According to circumstances, the boiler heating surface adjustment arrangement. J burner when necessary transformation to fit the gaseous fuel.
Factors that affect factors superheated steam temperature changes affect food factory superheated best price for coal fired steam boilers plant food temperature variation effects superheated steam boiler temperature variation food factory, 1, 2 changes, and the air volume ratio of 3 changes, burner fuel properties and 4, 6, 7, change the saturated steam temperature change and desuperheating water flow operation mode change in water temperature in the pulverizing system 5, the heating surface cleanliness variation boiler load variations. Change in fuel volatile carbon content, calorific value and the like: 1. Variations in the nature of the fuel. When the roughening coal, fuel combustion in the furnace a long time, the center of the flame increases, the steam temperature. When the fuel water is increased, the heat absorption of water evaporation furnace, the furnace temperature is lowered, the increase in humidity, but also increases the volume of the flue gas, the flue gas flow increases, reducing the superheater heat radiation, convection superheater heat absorption is increased. 2. And change the air volume ratio: when increasing the oxygen content of the furnace, the low temperature due to heat absorption of cold air, the furnace temperature is lowered, the furnace outlet temperature. At a total gas flow is constant, a change will also cause shifts air distribution steam temperature. When a low flow rate is insufficient, part of incomplete combustion of pulverized coal, the flame center is moved upward, the furnace exit gas temperature. 3, changing the operating mode of the burners and pulverizing system: operating system will result in an upper pulverizing the steam temperature is increased, the swing angle of the burner changes, the change in center of the flame, steam temperature changes.
Features of Chinese small electric boiler electric boiler has been continuously research new self, to the quality of the first, which has been pre-sales service our customers receive the praise, its research department has developed the latest technology and electric control system, economy , energy saving, environmental protection, security and other aspects of the world-class level. First, the introduction of an electric boiler, electric boiler automatic intelligent control techniques, unattended; 2, electric boiler work in a flexible manner, can be set to manual or automatic mode; 3, electric boiler can also need to set the automatic start date boiler , working hours, one day can be set ten different working periods, the boiler automatic, time to start each of the heating elements, the heating element switching cycle, the respective contact time, the same frequency, improving equipment life; 4, electric boiler analog control algorithms: automatic temperature (pressure) the PID, calculation, tracking, to ensure that the pump, the circulation pump start and stop automatically when the load change; can also be manually controlled; 5, chain-closing function; 6, alarm function: abnormal situation , automatic alarm; bell alarm is released, without exclusion of the fault, the alarm again; 7, appearance: boiler packaging with embedded frame structure, the entire outer surface of the spray, delicate and beautiful; 8, environmental run: no noise, pollution, high thermal efficiency, high quality and efficient boiler insulation materials, small heat loss, thermal efficiency greater than 98%; 9, compact, rational design and professional Into the manufacturing process, of the small boiler area, saving space; 10, range (electric hot water boiler, electric best price for coal fired steam boilers, electric storage boilers). 11, affordable, new electric boiler regardless of price, quality, lot better than the old-fashioned on environmental protection. Second, the characteristics of the boiler main body 1, made of high quality steel boilers, industrial boilers according to the manufacturer specifications painstakingly created; 2, vertical furnace, girth welds are welding, vertical boiler, X-ray detection girth weld; 3, using the boiler body quality and efficient insulation material, heat loss, thermal efficiency greater than 98%. 4, electronic control box and boiler complete supply, easy to install. 5, the heat-sensitive semiconductor material for high-tech heating body, a high electric conversion efficiency (97%) of coal up more than 20% cost savings, fuel savings of up to 40%. Power 1 minute heater hot water circulating from the tank to the radiator outlet temperature is above seventy degrees, thirty minutes radiator temperature of more than seventy-five. This is the use of non-pressure boiler circulating water heating system, a machine belt, not dry, is the development trend of modern boiler.
It is reported that Shandong Province to further promote the action of atmospheric pollutants governance, but also to "defend the blue sky strategy" escalating, the Shandong provincial government amended the new "Regional Air Pollutant Emission Standards" and other three local standards, as the province's mandatory local standards of environmental protection, on November 1, 2019 formally implemented.
1, to improve the standard index-related emissions, can improve the level of clean production, reduce pollutant emissions, Forced out of high-emission equipment, improve air quality. The revised standard canceled the densely populated high-polluting industries sewage privilege, the use of emissions phased strategy partition; divides a region of Shandong Province as the core focus, and general control zone, different regions perform different emission limits, based on the location of the enterprise partitioning control requirements.
2, a new round of defense blue sky "Strategy" will be ultra-low emissions standards covering all coal-fired boilers in Shandong Province, and will gradually promote the non-coal industry, requires iron and steel, coking industry emissions to meet ultra-low emission standards. Key building materials industry emissions control area cement, ceramics, lime, glass, etc. are also required to achieve ultra-low emission standards, the general control zone cement, ceramics, glass and other building materials industry emission requirements more stringent than the national standards.
3, changes in air pollutant emission standards in the current round of revisions is the biggest "air pollutant emission standards iron and steel industry." The new revised standard will help eliminate a number of small-scale, backward technology, compliance governance hopeless small-scale iron and steel enterprises, and guide the existing steel enterprises discharge standards by clean energy alternatives, etc., so as to promote Shandong Province, energy, industrial restructuring, improve the quality of atmospheric environment.
4, according to monitoring data, 2018, Shandong fine particulate matter (of PM2.5), particulate matter (of PM10), sulfur dioxide (SO2), (NO2) average concentration of nitrogen dioxide fell 14.0%, 8.5%, 33.3 %, 2.7%; the number of days of heavy pollution fell for 5 days. Wherein the fine particulate matter (of PM2.5) than the average concentration of 2013, 2015 decreased 50.0%, 35.5%.
According to the "2013 Shandong Province - 2020 air pollution control plan" in 2020, the province's basic ambient air quality standards, compared with 2010 improved by 50%. Since 2013, Shandong "broken wrist" environmental pollution, has released various standard 102.
