Free HRSG Design Tutorial - Ducting Pressure Losses

Ducting Pressure Losses. HRSG designers utilize ducting for many purposes in a system design. They are used for connecting flue gas plenums to stacks, distributing coustion air to burners, transfering flue gas to the HRSG or for bypassing the HRSG. The pressure losses through ducting pieces may be individually analyzed or the may be analyzed as a system. We will first explore ducting losses

Design Of Dual Pressure Heat Recovery Steam Generator For

Dual pressure HRSGs have been widely used because they showed higher efficiency than single pressure systems and lower investment cost than triple pressure HRSGs[3,4].The power generation and thermal efficiency of Coined Cycle Power Plants (CCPPs) depend strongly on the Heat Recovery Steam Generator design which links the gas cycle with the steam cycle. Therefore, the HRSG must be …

With a single-pressure HRSG, about 30% of the total plant output is generated in the steam tur-bine. A dual-pressure arrangement can increase the power output of the steam cycle by up to 10%, and an additional 3% can be achieved with a triple-pressure cycle [1]. Modern coined cycle power plants with a triple-pressure HRSG with steam reheat can easily reach thermal effi- ciencies above 55% [1

In general, HRSG cleaning is required when the gas-path pressure drop across the HRSG reaches 3 to 4 in. H 2 O over the “new and clean” condition. Once the need for cleaning has been established and an outage date determined, the next step is to select the optimal cleaning technology. The standard options are high-pressure water blasting, grit blasting, acoustic cleaning, and CO 2 blast
