Gas Flow Components

HRSGs and power boilers utilize baffling, tube ties, flow distribution grids and vanes to help direct gas flow through the heat transfer surfaces (tubes). If these components fail, boiler performance can decrease and pressure part damage can occur. The HRST team can design and supply the materials and drawings necessary to upgrade to a better arrangement.

What our clients are saying:

I like having HRST come to do our inspections every year. Seems like there are always things that come up that were not there before. It helps to be able to go back to previous inspections to see what was repaired or not repaired. The feedback from the inspection and findings helps us to keep the HRSG in top shape.
