石化系统的热电企业一方面具有热电行业的特点,另一方面又是为石油化工的生产服务,为其提供能源,同时很多热电企业还担负着工厂居民的生活能源供应。一般来讲,石化热电企业的生产管理有以下几个特点:一是供电供热同时并存。热电厂承担着工厂生产和厂区居民生活用电用热的供应任务。二是热负荷变化较大,供热源分散。由于石油化工生产的特点,热负荷在不断地变化,相对于电厂发电热负荷而言,具有较大的波动性,同时石油化工生产装置在生产过程中有部分余热可以利用,因此热源比较分散。
On the one hand, the thermoelectric power plant of the petrochemical system has the characteristics of the thermoelectric industry. On the other hand, it also serves the petrochemical production and provides energy for it. At the same time, many thermoelectric enterprises also shoulder the living energy supply of the factory residents. In general, the production and management of petrochemical thermoelectric enterprises have the following characteristics: First, supply and heat coexist. The thermal power plant undertakes the task of supply of heat for the production of the factory and the electricity consumed by the residents in the factory area. Second, large changes in heat load, heat source dispersion. Due to the characteristics of petrochemical production, heat load is constantly changing, compared with the power plant thermal load, with greater volatility, and petrochemical production plant in the production process, part of the waste heat can be used, so the heat source is more dispersed.
