Application Of Saturated Steam Generation Technology In Coal Chemical Steam System

Saturated steam generation technology is an approach of waste heat utilization and energy cascade utilization. Because of its wide application, the technology was universally concerned. Saturated steam generation technology is not only used for actual production, but also a universally applicable energy utilization technology for scientific research. At present, the saturated steam generation mainly concentrated in the steel industry, but there’s still a lot of waste heat resources industries and sectors have the potential to be utilized, where the key factor is the technology is not perfect. Moreover, China’s most saturated steam power generation applications is a high energy-consuming industries, the power generation technology, there are still some limitations in other industry applications, and there is a lack of ability to cross-reference to the shortcomings and lack of relevant project application, which is an urgent market needs and optimize the energy structure there is a huge contrast.The topic does a research of the theoretical basis for saturated steam generation technology, combines the status of the development and application at home and abroad, and proposes a program to solve the problem of a large number of by-product steam can’t be fully utilized in coal chemical industry by the use of saturated steam generation technology. The steam that could not be consumed and discharged to the atmosphere is used to the energy recycling, reducing environmental pollution on steam, at the same time, addressing the problem of echoed up and down of the whole plant steam pipes gateway. It not only makes the adjustment between stages easier, but also ensures the safety of the whole plant steam system reliable operation. Meanwhile, the topic gives a comprehensive overview about some key issues of the saturated steam generation technology, such as the last stage blades secondary droplets corrosion, steam parameters fluctuations, run variable condition, crew safety and thermoelectric devices supporting selected, and so on. Through literature research and field tests, we can propose ideas to solve the problems, and make an evaluation about the economic and environmental benefits of saturated steam to generate electricity.In this paper,2×CN25MW heat extraction condensing turbine generator of high-sulfur coal and clean use of oil-based electric integration demonstration projects of Shanxi Lu’an Mining the clean use of high-sulfur coal Lu’an Mining Oil is studied. The power station area of this generator sets not only can provide various levels of superheated steam to different technology devices, but also can generate electricity by using the waste heat steam from different technology devices. Among which, the medium-pressure saturated steam cogeneration module as an important part of the waste heat utilization is occupied with typical industrial turbine characteristics:Inlet parameters are restricted by upstream process units, cannot be self-regulate and can only adjust itself to adapt to the upstream parameter changes. Finally, on the basis of the whole plant steam parameters’ characteristic, we can propose the balance of whole plant steam pipe network, and make sure the thermoelectric devices supporting programs to provide technical guidance for the implementation of the project.This study provides an experimental basis and important reference for further research of saturated steam generation technology applications.
