Exhaust heat loss factors determines the size of the three: the exhaust gas temperature, excess air coefficient, and the cold air temperature. Wherein the excess air ratio of gas plc automatic control low pressure boiler is a major factor. Excess air ratio is too large a tremendous waste. A lot of cold air into the furnace inside, first reducing the temperature of the furnace, combustion conditions become unstable, but also increases the flue gas volume, increased heat losses. Calculations show that when the excess air ratio is increased to 3.0 from 2.0, heat losses to 4.5%. While increasing the drum Fan burden, so power consumption increases. In order to improve the gas boiler thermal efficiency, we must pay attention to and raise awareness of the serious dangers for the high excess air ratio caused by combustion in the regulation strictly control the excess air ratio, which is currently heating industry in areas often overlooked.
The medicines in a plurality of sub-Sheng enamel tray, bubbles were placed, with each tank and balling. The number and location should be loaded in the plc automatic control low pressure boiler maintenance records, so as not to forget to remove when put into operation. The desiccant should be placed in a furnace to close the respective valve soda immediately to prevent outside air from entering.
November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast plc automatic control low pressure boiler - premix wing-type vacuum condensing hot water boiler, with ultra-low nitrogen oxide emissions and excellent energy-saving effect with this honor. "Energy saving" was first presented in the "" Eleventh Five-Year "Plan", the entry point to do by reducing energy waste and reduce emissions in terms of both economic development and adhere to common development and environmental protection. Since 2015, the state has increased efforts to promote energy-efficient technology and equipment, mechanical and electrical products each year in all types of energy-saving aspects of the work of judges, party fast with a strong technical ability to create many types of environmentally friendly products, as the heavy regulars honor.
