SRC Burn Test in 700-HP Oil-Designed Boiler. Annex Volume E. Evaluation of Fabric Filter for Particulate Emission Control. Final Technical Report

摘要

Three types of Solvent Refined Coal Fuels namely, Pulverized SRC Fuel Solids, SRC Residual Fuel Oil and SRC Fuel Water Slurry were fired, one at a time, in a 700 HP boiler designed for oil firing. The purpose was to demonstrate the suitability of SRC Fuels in serving as an alternative to fuel oil and to evaluate the feasibility of fabric filters for control of emissions from SRC fuel fired boilers. Two types of fabric filters, namely a Pulse Jet, full scale Baghouse and a Reverse Air, pilot scale filter were tested. The Pulse Jet Baghouse was an existing full scale unit with a cloth area of 1924 square feet and a gas flow capacity of approximately 10,000 ACFM at 400 exp 0 F. The Reverse Air Pilot Filter was a bench scale, portable unit with a cloth area of 1 square foot and a gas flow capacity of up to 6 ACFM at 400 exp 0 F. This report presents the results of particulate mass emission rates, operating conditions and performance of the two fabric filters. The particulate emissions from all fuel types were easily controlled to less than 0.01 lb/million Btu within normal and conventional working range of the fabric filters and with no special or restrictive operating conditions.
