Waste Heat Boiler Preparation (Courtesy of Rentech Boiler Systems Inc.). Hydrostatic Testing. The equipment has been hydrostatically tested to a minimum of 1½ times the design pressure, in the factory, and copies of the Manufacturer's Data report, signed by the Authorized Inspector witnessing and evidencing the test has been forwarded to all jurisdictional bodies as well as to the Client.

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
Reusing waste heat for steam or power replaces the need for additional auxiliary-fired boilers. Every 1 MMBtu/hr recovered eliminates 410 tons of CO2 and 280 lbs each of NOx and CO annually to help meet energy efficiency, emissions reduction and decarbonization goals.
Waste Heat Recovery Boiler of Hazardous Waste Incineration--ZBG
waste heat recovery is to try to recover maximum amounts of heat in the plant and to reuse it as much as possible, instead of just releasing it into the air or a nearby river.

Waste Heat Boiler - an overview | ScienceDirect Topics
a waste heat recovery system compris-ing both steam and power turbines, and combined with utilising scavenge air energy for exhaust boiler feed-water heating. This paper describes the technology behind waste heat recovery and the potential for ship-owners to lower fuel costs, cut emissions, and the effect on the EEDI of the ship. Introduction
