Experience a new level of Tea Engineering

T&I Global Limited (TIGL) presents BLAZE, the truly energy efficient special alloy vertical tube bank air heater, specifically designed for low firing costs and minimum maintenance. Indigenously developed, BLAZE is the only heater made of fully fabricated High Alloy Steel tube banks, refractory brick arches and combustion chambers, thus eliminating castings and improving thermal efficiency.

Operating Principle

Flue gases drawn by an induced draught created over the grate by the ID fan and chimney, passes at critical velocities through a set of vertical tubes placed on either side of the grate, and this ensures optimum heat transfer in each pass. Ambient fresh air drawn from the back of the heater

 Optimum heat transfer due to the unique ‘high temperature resistant’ SS and alloy steel tube bank combination

 Improved tube bank design and optimum fuel combustion rates ensure at least 15-20% reduction in fuel consumption

 Vertical design ensures less scale/soot formation inside the tubes and enables easy cleaning

 Minimal recurring maintenance cost since all parts are fully fabricated with heavy duty steel

 Unique construction ensures easy and faster installation while reducing down time

 Temperature control Unit for maintaining uniform temperature to dryer

 Compact design for optimum floor space economy

 Suitable for all dryers (Conventional , VFBD, Combination)

 Truly multi fuel, can be operated with solid fuels like coal, leco, firewood, briquettes, bagasse, etc

 No replacement of CI arches and other castings

 Four Pass and Five Pass versions available.

** Depends upon drier inlet temperature, altitude, drying temperature and manufacturing method of the factory
* 5 HP more needed when operating indirect heater to meet extra pressure drop in the hot air generator Due to a continuous process of development the design and specifications are subject to change without notice
