It is the opinion of the authors that the ideal test result would be obtained if reaction temperature must be over 1 500℃,condensing temperature about melting point,reducing gradient of condensing temperature,and previously coking required for raw material(Change of pressure in the vessel can reflect the reaction conditions).
通过改变试验条件 ,用真空碳热还原煅白得到了生长良好的金属镁的晶体 ,认为要得到理想的试验结果 ,必须使反应温度高于 1 5 0 0℃、冷凝温度在镁的熔点附近 ,减小冷凝的温度梯度 ,反应过程中炉内压力变化能反映反应的进行情况 ,物料要先进行焦
When it is applied in condensing gas-fired boiler,it is not only reducing the combustion-supporting air,but also greatly increasing the content of vapour in smoke and heightening the dew point.
富氧燃烧是一项节能高效的燃烧技术,应用于冷凝式燃气锅炉时,不但能够减少助燃空气量,而且大大提高排烟中的水蒸气含量,提高烟气露点温度,有利于回收烟气中的汽化潜热。
