Waste Heat Boiler Tube Leakage - Metal and Metallurgy

We recently had to shutdown our plant due to tube leakage in our Waste Heat Boiler(WHB). Upon vessel opening we observed visible leakage from at least 01 tube as the refractory and heat shield adjacent to it was damaged. Evidence suggested that upon leakage BFW water flashed and damaged the refractory on shell and tube sheet.

Use Feedwater Economizers for Waste Heat Recovery

Use Feedwater Economizers for Waste Heat Recovery A feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to incoming feedwater. Boiler flue gases are often rejected to the stack at temperatures more than 100°F to 150°F higher than the temperature of the generated steam.

Boiler Economizers and Waste Heat Recovery

Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%.

Blowdown Heat Recovery System: Captures waste heat from the boiler surface blowdown to increase make-up water temperature (sensible heat) going to the feed-water tank. Continuous boiler surface blowdown heat recovery is the most optimized method of controlling total dissolved solids (TDS) levels within the boiler because it captures otherwise
