Engineering development of advanced coal-fired low-emission boiler systems. Quarterly technical progress report, April 1--June 30, 1993
Abstract
Preliminary sketches of the furnace setting with dimensions and other appropriate data was distributed to appropriate boiler design groups. The purpose of this work was to define and/or establish unique mechanical and support requirements and furnace water circulation requirements. A preliminary convection pass arrangement and heating surface requirements were established. Initial computer runs indicate, as expected, that establishing even a preliminary arrangement to meet steam duty requirements was going to be a challenge. This due to slightly lower furnace exit gas temperatures (result of NO{sub x} control conditions) and higher final steam temperatures (results increasing plant efficiency) than typical of conventional design. Work on the furnace and convection pass design for the base preliminary unit was completed only to the extent necessary to identify design deficiencies, prepare an arrangement drawing and determine budgetary cost. Engineering work has been completed to the extent planned in this subtask for the base preliminary unit, Advanced Overfire Air, including preliminary designs for the furnace, convection pass, pulverizers, airheaters, flues and ducts, preliminary general arrangement drawings, and budgetary cost estimates. Work is nearly complete on design of the LEBS unit control system based on control methods and philosophy established in the NO{sub x} Control Subsystems.more »
