Problem

Energy is a major input in the cement manufacturing process & it is met by setting up a Captive Thermal Power Plant for efficient operations. The heat generated through Rotary Kiln preheater (PH) & After quenching cooler (AQC) exhaust hot gases for power generation. Around 30%-40% of the power requirement of the cement plant can be fulfilled by using this waste heat for power generation. It optimizes the overall production cost.

Exhaust gas is generated at very low static pressure in large ducts.
Low velocity & high temperature from 150⁰C to 400⁰C
Differential pressure flowmeters don’t work at low flow rates.
Existing DP flowmeter has high-pressure drop & low accuracy.

Solution

Leomi – 586 Insertion Thermal Mass flowmeter

High turndown down ratio of 100:1 against 4:1 of the existing installation.
No pressure drop.
High accuracy against DP flowmeter
Works well even in high temperature & low velocity
Doesn’t require a shutdown for installation
No maintenance than the existing flow meter used.
