脉冲抛动式炉排的PLC控制

The PLC Control of pulse Hearths

垃圾焚烧发电在我国还处于起步阶段.PLC技术原来主要用于顺序控制方面,随着微电子、大规模集成电路、计算机、通讯技术的发展,PLC已具备了中小型DCS系统所具有的功能,而造价大大降低.本文主要介绍了西门子公司S7-400系列PLC在南海垃圾电厂脉冲抛式炉排自动控制系统中的典型运用.

Burning garbage to generate electricity is still in the start stage in our country.The PLC technique was primarily used for the control in proper order. Along with the development of micro-electronics, large-scale integrated circuit, computer and communication technique, the PLC has already had the function of the medium-sizes DCS system.But its price is consumedly lower.In this paper is mainly introduce the S7-400 series PLC of Siemens company, which have been successful applied at the pulse hearths autocontrol. Nanhai garbage electricity power plant.
