Heat recovery from flue gas of coal fired installations with reduced pollutant emission - the Zittau process

Journal Article:

Abstract

Reviews the technology applied in the Zittau process for flue gas heat recovery and flue gas desulfurization in small brown coal fired power plants. Steam generators have a capacity of 6.5 or 10 t/h, low grade fuel with 8.2 MJ/kg calorific value is combusted. Technology has been developed on an experimental 10 t/h steam generator since 1986; an industrial 6.5 t/h prototype steam generator is now in operation achieving 95% SO{sub 2} removal from flue gas with 5600 to 7800 mg SO{sub 2} per m{sup 3} of dry flue gas. The Zittau technology is available in 3 variants: with maximum waste heat recovery, with partial waste heat recovery or without waste heat recovery and only wet flue gas scrubbing. Two flowsheets of flue gas and suspension circulation are provided. The first variant recovers 25.7% of nominal heat capacity (1.1 thermal MW from a 4.2 MW steam generator with 6.5 t/h steam capacity), the second variant recovers 6.5% of waste heat by reducing heat exchangers to 20% of the size of the first variant. Flue gas suspension scrubbing utilizes power plant ash, which is capable of absorbing 50 to 70% of SO{sub 2}, additional 25% SO{sub 2} removal is achieved by  More>>
