Publication number: 20160236136Abstract: Methods and systems for reducing emissions produced in a combustion system are described. A sorbent material is introduced into the emission gases flowing from the combustion system. Sound waves are also applied to the emission gases in the flow path. The sound waves can be introduced into the emission gas flow path at a location upstream from where the sorbent is introduced into the emission gas flow path. The sound waves can also be introduced into the emission gas flow path such that the sound waves travel in a downstream direction in the flow path. The emissions can include Hg and acid gases such as SO2. The sorbent material can be trona or activated carbon. The sound waves enhance mixing of and mass transfer between the sorbent and pollutants in the gas thereby reducing the amount of sorbent necessary to reduce harmful emissions.Type: ApplicationFiled: February 12, 2015Publication date: August 18, 2016Inventor: Danny S.

Patent number: 9279627Abstract: A sootblower having a nozzle that includes one or more deep reaching jets aligned with its respective platen bank to clean slag deposits inset from the leading edge of the platen bank. The nozzle also includes one or more edge cleaning jets substantially angled with respect to the platen bank for cleaning the leading edges of the platen bank. For most applications, the major axis of the sootblower is perpendicular to the major axis of its respective platen bank, resulting in a sootblower with a nozzle having angled and perpendicular jets, referred to as angled-perpendicular nozzles. The jet sizes are selected to balance the opposing components of force perpendicular to the sootblower to avoid the imposition of torque on the lance.Type: GrantFiled: May 27, 2014Date of Patent: March 8, 2016Assignee: CLYDE BERGEMANN POWER GROUP AMERICAS INC.Inventor: Danny S. Tandra

Publication number: 20130312673Abstract: A temperature sensing sootblower that may be configured as a modification to an existing sootblower or a specially constructed sootblower that, in addition to its normal soot blowing functions, has the capability to measure the flue gas, lance tube, and/or cleaning fluid temperatures. One or more thermocouples or other temperature measuring devices are carried by the soot blower lance tube that is inserted into the boiler. This allows for the temperature of the flue gas, lance tube, and cleaning fluid to be measured as the sootblower lance tube is inserted into and retracted from the boiler. Multiple temperature measuring devices may be located on the sootblower lance to measure the temperature across heat transfer surfaces and at different locations along the lance tube. A data transfer device transmits the temperature measurements from the rotating thermocouple to a non-rotating data acquisition unit for use in boiler cleaning and other operations.Type: ApplicationFiled: January 21, 2011Publication date: November 28, 2013Inventors: Charlie L. Breeding, Danny S. Tandra, Bruce K. Townsend, Charles A. Strawn
