Kumera Heat Recovery Steam Dryer

Kumera Steam Dryer has been the industrial standard in concentrate drying for over twenty years. Now, in 2021, the new era of energy efficiency has been reached with introduction of Kumera Heat Recovery Steam Dryer.

Kumera Heat Recovery Steam Dryer is developed to meet even higher efficiency requirements than before. It is benchmark technology for energy-efficient water removal. Kumera Heat Recovery Steam Dryer is clean and sustainable drying technology which can increase the existing drying capacity by up to 40 % without any additional use of primary energy or steam.

Benefits of the Kumera Heat Recovery Steam Dryer

represents the latest development, increases drying efficiency to a higher level than ever before
can utilize low calorific heat sources, exhaust vapour from Kumera Steam Dryers or other waste heat sources
minimizes fuel consumption, off-gas generation, and dust emissions
CO₂ emission reduction is significant compared to any direct fired drying process utilizing fossil energy sources and operation cost is limited to utility power
high capacity of concentrate feed rate at 100 t/h ^(*
high capacity of water evaporation rate at up to 10 t/h ^(*
superior energy efficiency is answer for tightening environmental and energy requirements

^*) temporary steam boost

The first Kumera Heat Recovery Steam Dryer with capacity of 60t/h was commissioned in 2021. It operates using exhaust steam from an existing Kumera Steam Dryer, which means the operational cost of Kumera Heat Recovery Steam Dryer is limited to utility power only. Environmental benefits are significant since no additional fossil fuels are needed.

Kumera Heat Recovery Steam Dryer is a novel concept that can utilize heat sources with low calorific value to increase drying efficiency to a higher level than ever before. This design is an advanced iteration of the Kumera Steam Dryer technology which has been the best available drying method for over two decades, and with 30 references around the Word. Kumera Steam Dryers are suitable for drying minerals, metal concentrates, organic materials and solid fuels with broad range of moisture contents and even corrosive compounds.
