Thermax’s Bi-Drum FBC boilers and ESP reduce coal usage and emission compliance for a chemical industry

Project overview

An Indonesian manufacturer of nucleotides, lysine, and MSG aimed to improve boiler efficiency and reduce emissions from its coal-based operations.

Thermax upgraded the facility with a more efficient fluidised bed combustion boiler, enhancing performance and lowering coal consumption. The successful implementation led to repeat orders and further emission control upgrades, supporting improved efficiency and regulatory compliance.

Challenges

In 2016, an Indonesian manufacturer of nucleotides, lysine, and monosodium glutamate (MSG) relied on coal-based chain grate boilers, facing challenges with low efficiency and high emissions.

Solution

Thermax replaced one of their inefficient boilers with a Bi-Drum fluidised bed combustion boiler, offering better combustion, reduced coal usage, and improved operational reliability.

Result

The new boilers reduced coal consumption by approximately 15–20%. Pleased with the performance, the customer placed a repeat order for 3 x 35 TPH Bi-drum boilers. Thermax also installed four electrostatic precipitators (ESPs) on their existing boilers to reduce emissions by less than 100 mg/Nm³, ensuring regulatory compliance.
