  • Method for reducing fireside tube deposition and boiler sootblowing requirements
    Patent number: 4639381
    Abstract: Method and apparatus for reducing the sootblowing requirements for boiler heat exchanger tubes which also reduces boiler downtime and production losses as well as energy requirements. The method involves the steps of programming the feeding of chemicals to the boiler in timed relation to a sootblowing cycle to establish a cleavage plane on the tube surfaces. The apparatus includes the feeding of a measured amount of powdered chemicals to the boiler following each sootblowing operation, which includes a storage vessel charged with a measured amount of chemical that is emptied during a chemical application cycle.
    Type: Grant
    Filed: June 19, 1985
    Date of Patent: January 27, 1987
    Assignee: Nalco Chemical Company
    Inventors: Robert B. Wierzba, Robert G. Snyder, Blaise H. Kleefisch
