Embodiment Construction

[0015]The invention will now be described with reference to the drawing figures, in which like reference numerals refer to like parts throughout. An embodiment in accordance with the present invention provides an apparatus for removing ash from pressure parts of a Radiant Synthesis Gas Cooler (RSC). The embodiments in accordance with the present invention may include a rapper actuator, a striker pin, a striker target, and wear plates.

[0016]FIG. 1 is a perspective view illustrating a rapper mechanical arrangement 10, according to one embodiment of the invention. The components are a rapper actuator 12, a striker pin 14, and a striker target assembly 16. The rapper actuator 12 can be pneumatic or electromagnetic. The striker pin 14 is spring loaded to assure that the striker pin 14 is in constant contact with the striker target assembly 16. The striker target assembly 16 is a composite assembly of parts described herein.

[0017]The rapper actuator 12 attaches to a flange 18 that is moun...

Abstract

An embodiment in accordance with the present invention provides a device and method for removing ash from an interior surface of a radiant synthesis gas cooler. The device for removing ash includes a rapper actuator, a striker pin coupled to the rapper actuator including a proximal end and a distal end, and a striker target assembly disposed such that a proximal surface of the striker target assembly is in contact with the distal end of the striker pin and a distal surface is in contact with the surface of the radiant synthesis gas cooler.

Description

FIELD AND BACKGROUND OF THE INVENTION[0001]The present invention relates generally to the field of coal gasification and, to a Radiant Synthesis Gas (syngas) Cooler (RSC) for an Integrated Gasification Combined Cycle (IGCC) power plant. More particularly, the present invention relates to a rapper to remove ash from pressure parts within the RSGC.[0002]The Radiant Synthesis Gas Cooler (RSC) is a component of an Integrated Gasification Combined Cycle (IGCC) power plant. Hot gas and molten ash from the gasification process enter the top of a vertical pressure vessel. Inside the vertical pressure vessel are pressure parts that cool the gas and generate steam for the steam turbine cycle. Ash attaches to the pressure parts in a process called ash deposition. Ash deposition reduces the heat transfer through the pressure parts and steam flow to the turbine. Therefore, in order to maintain power output for the plant it is desirable for at least some of the ash to be removed from the pressure...
