Waste Heat Recovery Boilers

Dynepro’s Technology team has offered a sustainable solution to a glass major to recover the heat from waste gases exhausting from their float to generate 1 MW of power. The nitrogen rich gas of around 85000 Nm^3 per hour with a temperature of 400 to 420 Deg C exhausting from the process is let in to a Single drum bottom supported Vertical design water tube boiler equipped with an array of heat transfer areas like Evaporator, Economizer and Superheater. The steam of 9.8 TPH at 25 Kg/Sqcm (g) pressure and 230+/-10 Deg C Superheat is generated which is then let in to a multistage straight condensing Steam turbine with integrally geared radial split with built up rotor construction which is the optimum selection for this application. The generator is of 11 KV output. The complete system is equipped with all Safety features and being operated through PLC based control system. This solution has achieved higher efficiency in recovering the waste heat from waste gases by maximizing the energy output and becoming more sustainable by reducing its carbon footprint.
