我厂是日加工甜菜1500吨的中型糖厂，平均日产结晶汁汽（以下简称尾汽）约320吨，由于其温度在85℃左右，热值较低，多年来一直不能充分利用。为了维持正常的真空煮糖条件，还必须用循环水冷凝这些尾汽，为此我厂每小时至少消耗400吨循环水（包括补充的冷水）。由于尾汽有热值? Our factory is a medium-sized sugar factory that processes 1500 tons of beets daily. The average daily production of crystalline steam (hereinafter referred to as tail gas) is about 320 tons. Due to its low temperature value around 85°C, it has not been fully utilized for many years. In order to maintain normal vacuum boiling conditions, the tail gas must also be circulated with recycled water. For this purpose, our factory consumes at least 400 tons of recycled water per hour (including supplementary cold water). Because of tail gas heating value?
