waste heat boiler in sulfur recovery unit

Sulfur Recovery Units - BORN Inc.

Each 3-Tier unit was equipped with a combustion burner, combustion chamber, turning plenum, waste heat boiler and steam drum. Generally, the combustion chamber and the waste heat boiler are arranged in a horizontal configuration. In this 3-Tier design, the waste heat boiler is stacked above the combustion chamber and connected by a turning plenum to minimize the overall footprint of the unit. The gas side of the unit was provided with internal refractory. The water side was externally insulated.

Downsizing a Claus Sulfur Recovery Unit - Refining Community

Waste Heat Boiler The boiler is a heat transfer device. There will be too much surface area within the boiler to maintain the original design outlet temperature. If the outlet temperature drops below the sulfur dew point of the boiler outlet stream, the sulfur will be condensed within the boiler. Some boilers have sulfur rundown legs and some do not.

Why do waste heat boilers fail? - Porter McGuffie, Inc

Typically waste heat boilers (WHBs) fail due to three factors: excessive tempera- ture, excessive mass flux rate and exces- sive water-side fouling 1. Similar to the racing industry, the sulphur industry has increased temperatures and mass flux (process flow) rates to obtain greater unit capacity.

Sulfur is an extremely useful element. Its largest

by generating steam in a waste heat boiler. The gases are further cooled by producing low-pressure steam in a separate heat exchanger, commonly referred to as a sulfur condenser. This cools the hot gases to approximately 325°F, condensing most of the sulfur which has formed up to this point.
