total heating surface area of boiler

The Circulating fluidized bed coal fired total heating surface area of boiler contains mainly particles of an inert material, like sand and ash, including particles of SO2 sorbent. The coal content in a fluidized bed is not considerable, it is only from 3 to 5% of the whole mass of the bed.

Saturated vapor pressure gas steam total heating surface area of boiler is how strong is the replacement gas is typically adjusted to replace Cube saturated vapor pressure. Increase in natural gas, gas steam boiler heat storage capacity increase in a greater number of saturated steam occurs, so that the pressure increases, natural gas will lead to reduction of the saturation vapor pressure weakened. Second, the replacement gas steam boiler reveal the degree of closure of the auxiliary valve saturated steam piping may be replaced with saturated vapor pressure (valve opening pressure ambassador weakened, so that the valve off a small pressure increase)

November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast total heating surface area of 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.
