我国“西气东输”工程的设施,为燃煤锅炉使用天然气这一洁净能源提出了新的技术问题。解决好燃烧天然气这一能源变化问题,必须首先研究水循环,为燃煤锅炉改造成燃气锅炉提供燃烧(流场和温度场)设计参数。当前,将燃煤锅炉改造成燃气锅炉在我国部分地区已见报道,但限于改造方式简单,且对锅炉水循环、流场和温度场均没有很好研究,不能避免因天然气燃烧快和热量集中而使锅炉过热、过烧,同
The facilities of China’s “West-East Gas Transmission Project” put forward new technical problems for the clean energy of coal-fired boilers using natural gas. To solve this energy change problem of burning natural gas, we must first study the water cycle and provide combustion (flow field and temperature field) design parameters for the conversion of coal-fired boilers into gas-fired boilers. At present, it has been reported in some areas of our country that the coal-fired boiler is transformed into a gas-fired boiler. However, it is limited to the simple mode of reform and has not been well studied on the water circulation, flow field and temperature field of the boiler. Boiler overheating, over burning, with
