ZVU Engineering waste heat boilers are designed in fire tube or water tube arrangement, both in horizontal and vertical execution. The design is featured by their heavy duty construction. A particular attention is paid to problems of geometry of the space for steam production, a space for separating water entrained in steam and the design of internal circulation conditions in evaporators.


Waste heat recovery boiler uses waste flue gases for steam production, so this economizer is also work on these varying parameters like gas flow rate, temperature variation, pressure variation, amount of ash content in flue gases. By considering these parameters we are going to design the economizer for waste heat recovery boiler.

Boiler – Fundamentals and Best Practices

"WASTE HEAT RECOVERY TO INCREASE BOILER EFFICIENCY USING BAGASSE AS FUEL" Prepared & Presented by: Kaare MANYAMA JACOB MSc in Energy Engineering 20/01/2017 INTRODUCTION Growing cost of fuel and the need to fulfill the requirements of the Kyoto Protocol force the majority of countries, even with temperate climate, to revise their attitude to district heating systems.

Steam Generators and Waste Heat Boilers: For Process and

Waste heat boilers recycle the heat, steam, or combustible by-products of other processes to provide energy. Equipment Design Because of their unconventional fuel source, waste heat boilers have a unique design. Waste heat boilers generally have larger intake capacities than other types of boilers because the entering fuel is not very efficient.

Steam boilers and waste heat boilers

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.
