Abstract
With the development of our national economy,in power production in bring the
pollution of the environment is more and more serious. NOx discharge is now
serious imposed on in accordance with the flue-gas dischargestandard of fossil power plant
published by the state because of its detriment with Nox to the environment.,and in
environmental policy,plan of electricity, electricity market rules, denitration price
compensation to existing coal-fired generator set denitration reconstruction positive support
and policy regulation control Therefore,the applicatim of the denitration technology should
be strongly extended。Huaneng jiutai power plant is planning for active duty 2 X 660MW
coal-fired electric group perform denitration renovation to comfirm with national standard.
This article has first analyzed the domestic and foreign De-NOx technology
development background, and introduces the denitration technology in coal-fired power
plant on the actual implementation of the existing coal-fired power plant denitration
renovation, denitration technology in actual operation, the existing Jiutai power plant
infrastructure, In this paper, the Jiutai power plant denitration technology reform scheme is
analyzed and designed，Including Analysis of the risk of denitration transformation, the
choice of equipment and materials and installation process, after transforming effect the
performance of the existing equipment and so on ，The Jiutai power plant denitration
transformation&39;s impact on the environment is analyzed，Including the denitration may bring
in the surrounding environment such as air pollution, noise pollution, and the environmental
benefits of denitration。the social impact of The Jiutai power plant Denitration is analyzed,
Including may cause disputes and social benefit analysis , The economic benefits of
denitration transformation are analyzed, Including the denitration project cost, operation cost
and future earnings forecasts, etc. In the above analysis, Using the power plan a lot of testing
data and daily operation data and research on the existing technology at home and
abroad,market for equipment and raw materials market investigation, and consult the
relevant technical specifications and standards,, According to the state and jilin province
department of the relevant laws, regulations, system and policy, the more objective and
comprehensive analysis was carried out on the project denitration. Based on the Jiutai power
plant denitration reconstruction project of technical analysis, financial benefit analysis,
environment benefit analysis and social benefit analysis, it can be Huaneng jiutai power
plant 2X660MW thermal power unit denitration renovation project is feasible.
