摘 要

随着我国经济的快速发展，能源需求量迅速增长，提高能源利用效率成为我国能源工作的重点。目前，国内规模以上玻璃瓶企业有500多家，多数企业的产能在10w吨以下。由于行业集中度太低，大多数企业的盈利能力不强，没有能力进行节能和环保方面的改造。因此，玻璃余热回收迫在眉睫。

作为建材行业的能耗大户，玻璃的生产需要消耗大量的能源。燃料释放热量后，35%～40%被玻璃液吸收，通过窑体表面散热的损失约为20%～25%，而通过排烟所带走的热量造成的损失可达30%～40%。可见，在玻璃窑中，烟气余热利用的潜力巨大，有效利用这一部分的热能， 将对企业的经济效益和节能减排产生显著的促进作用。

本论文设计的是2.5MPa玻璃余热锅炉，冷流体是水，热流体是玻璃废气，主要设计内容包括过热器、蒸发器、省煤器。热力计算中，采用理论计算法，根据给定的冷热流体进出口参数，确定其他部件的介质进出口参数，再计算各个部件的换热系数，算出换热面积。并且对其进行阻力、压降和强度计算。

The Design of 2.5MPa glass waste heat boiler

Abstract

With the rapid development of economy, rapid growth in energy demand, increasing energy efficiency has become the focus of China's energy work. At present, the domestic glass enterprises above designated size has more than 500, most enterprises can produce 10w tons. As the industry concentration is too low, the majority of corporate profitability is not strong, there is no capacity for energy saving and environmental protection. Therefore, glass waste heat recovery is imminent.

As a major energy consumer in the building materials industry, glass production requires large amounts of energy. After the fuel release heat, 35% to 40% is absorbed by the glass, by the kiln surface heat losses of about 20% to 25%, while the loss carried away by exhaust heat could reach 30% to 40%. Seen in the glass furnace, the flue gas waste heat utilization potential is huge, efficient use of energy in this section will have a significant role in promoting economic efficiency of enterprises and energy conservation.

This paper is designed to 2.5MPa glass waste heat boiler, cooling fluid is water, thermal fluid glass waste gas, the main design including superheater, evaporator, economizer. Thermodynamic calculations, theoretical calculations, based on import and export of hot and cold fluids given parameters, determines the media import and export parameters of other components, then calculate the heat transfer coefficient of each component, calculated heat transfer area. And its resistance, pressure drop and strength calculations.

Key words: glass;waste heat boiler;superheater; evaporator;economizer

1. 前言

目前，国内规模以上玻璃瓶企业有500多家，多数企业的产能在10w吨以下。即使是玻璃器皿行业产销量居国内第一的安徽得力公司，其年产能也仅8w多吨，占国内市场份额5％左右。由于行业集中度太低，大多数企业的盈利能力不强，没有能力进行节能和环保方面的改造。因此，玻璃余热回收迫在眉睫。作为建材行业的能耗大户，玻璃的生产需要消耗大量的能源。燃料释放热量后，35%～40%被玻璃液吸收，通过窑体表面散热的损失约为20%～25%，而通过排烟所带走的热量造成的损失可达30%～40%。可见，在玻璃窑中，烟气余热利用的潜力巨大，有效利用这一部分的热能， 将对企业的经济效益和节能减排产生显著的促进作用。
