Evaporative capacity of 10t/h of fuel gas steam boiler Design
Abstract: Boilers as an energy conversion equipment, in industrial production has been widely used. It does this by coal, oil or natural gas combustion release of chemical energy, and heat the heat transfer through the water, the water heating (or into steam), hot water direct supply to the industrial production and civil life, heating, so the main boiler mandate: to fuel the chemical energy into heat energy the most effective.
The graduation project topic is Evaporative capacity of 10t / h of fuel gas steam boiler Design, belonging to the natural circulation water tube boiler. Boiler design led by the spirit of the boiler operation safety and reliability criteria for design features. Considering combustion, heat transfer, gas and air as well as dynamic properties of working fluids and wear and corrosion. In the boiler design process, the main consideration is to ensure that the furnace fire, furnace heat radiation sufficient gas burnout degree and a reasonable speed and exhaust gas temperature. 源自六@维%论!文^网~加7位QQ3249`114 www.lwfree.cn
Throughout the design process as a technical support for the thermodynamic calculation, calculation of strength and wind resistance calculation smoke. Thermal calculation includes the furnace, burn room, boiler tubes and the provincial gas. Besides, Use of CAD, to complete the total Figure boiler and auxiliary equipment Figure.
Keywords: thermodynamic calculation; strength calculation; smoke wind resistance calculation
