Filed:

Jul 31, 2001

Appl. No.:

09/918924

Inventors:

E. Larry Beaumont - Littleton CO
Larry D. Richardson - Delmar NY
Kevin G. Rousseau - Windsor MA

Assignee:

ECO/Technologies, LLC - Albany NY

International Classification:

F23N 518

US Classification:

110238, 110233, 110218, 110219, 110185

Abstract:

A system and method for treating, injecting and co-combusting sludge in a municipal waste or other solid fuel combustor. The system includes a sludge receiving and treatment module and a sludge injection and combustion module. The sludge is received and stored in one or more storage hoppers where its moisture content is monitored and varied to obtain a sludge having a desired moisture content. The treated sludge is then pumped to a furnace injection nozzle where it is preferably atomized with steam and sprayed into the combustion zone of the furnace. Improved odor control in sludge handling is also provided by a storage tank and a sludge tanker trailer each having an air diffuser for mixing and aerating the sludge and a filter system for filtering odors.

Abstract:

A system and method for treating, injecting and co-combusting sludge in a municipal waste or other combustor is disclosed. The system includes a sludge receiving and treatment module and a sludge injection and combustion module. The sludge is received and stored in one or more storage hoppers where it is first diluted with a liquid and subsequently mixed to a desired homogeneous consistency suitable for pumping. The high liquid content sludge is then pumped to a furnace injection nozzle where it is preferably atomized with steam and sprayed into the combustion zone of the furnace. The disclosed system and method increases sludge moisture content and controls the solids content of the sludge to control furnace temperature.
