Cyclone Boiler - an overview | ScienceDirect Topics

Water-cooled vibrating grate boilers for fixed-bed combustion is a well-known technology for power generation from wood residues. Based on natural circulation, these boilers are designed to burn low-heating-value (LHV of about 13.8 MJ/kg) wood residues, with 30% humidity. Wood fuels could be used in the grate combustor without big problems, but

Selective catalytic reduction - Wikipedia

Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2 O).A reductant, typically anhydrous ammonia (NH 3), aqueous ammonia (NH 4 OH), or an urea (CO(NH 2) 2) solution, is added to a stream of flue or exhaust gas and is reacted onto a catalyst.As the reaction drives toward

Rich Reagent Injection (RRI) - Fuel Tech Inc

Rich Reagent Injection (RRI) Process. Rich Reagent Injection (RRI) is the process of adding NO x reducing agents in a staged lower furnace to reduce the formation of NO x.This is accomplished by injecting urea into the fuel-rich region of a furnace, where the reducing conditions and low oxygen levels in the lower furnace make RRI ideal for NO x reduction. . The combustion process is then
