北京焦化厂现有58型65孔大型焦炉四座,日产焦炭约5000吨。在炼焦生产过程中有大量余热生产。其中,煤气初冷水余热在数量上仅次于熄焦余热,占焦炉总耗热量的35%左右。如何充分利用这部分余热,对提高焦化厂的热能利用率具有重要意义。近年来,北京焦化厂在利用余热资源方面做了很多工作,除煤气上升管加了汽化冷却装置外,还部分利用了循环氨水余热用于厂区采暖。1981年底又提出了把煤气初冷水余热供垡头居住区采暖的初步方案。计算的最终供热面积为60万平方米。 Beijing Coking Plant currently has four 58-seat 65-hole coke ovens with a daily output of 5,000 tons of coke. There is a large amount of waste heat production in the coking production process. Among them, the amount of residual heat of the gas first cold water is second only to quench heat, which accounts for about 35% of the total heat consumption of the coke oven. How to make full use of this part of waste heat is of great significance to improving the utilization of thermal energy in coking plants. In recent years, Beijing Coking Plant has done a lot of work in utilizing the waste heat resources. In addition to the gas rising pipe and the vaporization cooling device, some recycled ammonia waste heat is also used for heating in the plant area. At the end of 1981, it also proposed a preliminary plan for heating the waste gas from the initial cold water for heating in Shantou residential area. The final heating area calculated is 600,000 square meters.
