Calorie HNT design,
manufacture, supply, install and commission heat / waste heat
recovery system on turnkey basis. These type of systems are custom
built and strictly as per individual customer or application or
industry requirement. The recovered heat can be utilized in many
application, which in turn is an energy saving.
A waste heat recovery
unit is an energy recovery heat exchanger that recovers heat from
hot streams with potential high energy content, such as hot flue
gases from a diesel generator or steam from cooling towers or even
waste water from different cooling processes such as in steel
cooling.

Recuperators: This name is
given to different types of heat exchanger that the
exhaust gases are passed through, consisting of metal
tubes that carry the inlet
gas and thus preheating the gas before entering the
process. The heat wheel is an
example which operates on the same principle as a
solar air conditioning unit. |
|
|
Regenerators: This is an
industrial unit that reuses the same stream after
processing. In this type of heat recovery, the heat is
regenerated and reused in
the process. |
|
Heat pipe exchanger: Heat
pipes are one of the best thermal conductors. They
have the ability to transfer heat hundred times more
than copper. Heat pipes are
mainly known in renewable energy technology as being
used in evacuated tube
collectors. The heat pipe is mainly used in space,
process or air heating, in waste
heat from a process is being transferred to the
surrounding due to its transfer
mechanism. |
|
Thermal Wheel or rotary
heat exchanger: consists of a circular honeycomb
matrix of heat absorbing material, which is slowly
rotated within the supply and
exhaust air streams of an air handling system. |
|
Economizer: In case of
process boilers, waste heat in the exhaust gas is
passed
along a recuperator that carries the inlet fluid for
the boiler and thus decreases
thermal energy intake of the inlet fluid. |
|
Heat pumps: Using an
organic fluid that boils at a low temperature means
that
energy could be regenerated from waste fluids. |
|
Run around coil: comprises
two or more multi-row finned tube coils connected to
each other by a pumped pipework circuit. |
Heat recovery systems are basically of two types, air-air heat
exchange and air-water heat exchange. The multi-step heat recovery
unit can fully utilize the energy after being best on the
requirements of environment and process technology. Air-Air heat
recovery unit heats the air by using the remaining exhaust heat
from hood so as to reach the purpose of recovering the heat
energy. The heat recovery unit is in pipelaid structure, which is
easy to clean and lasts a long life. The pipe and the panel is
connected by the expanded pipe or special rubber-alloy joint. |
