An automated chemical storage and chemical feed system for a use station to chemically treat and monitor a process at a use station where the process is being run, including one or more base chemical supply tanks at the use station storing chemicals and intermittently or continuously feeding the chemicals to the process. A level sensor is provided in each base tank to determine the chemical level and to deliver a signal to a control and processing unit. Sensors may be provided on the process for providing chemical condition information to the control and processing unit. A telemetry system receives the information from the control and processing unit and transmits it to a supply station where the information is recorded and read out to monitor the chemical supply in the base tank and to monitor the chemical condition of the process so that the chemical feed may be adjusted as needed and so that further chemical may be delivered to the use station to be introduced into the base tank and maintain an adequate supply to prevent interruption of the process. Refill tanks are shipped from the supply station to the use station, transported to the base tank, and emptied into the base tank. Thereafter, the refill tanks are returned to the supply station to be refilled.

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.
