Today, coal cost is impacting heavily on production costs. Local company Boiler Combustion Technology (BCT) realised the huge potential in developing alternative combustion control technology for coal fired boilers in the quest for energy efficiency. BCT is claiming savings of up to 25% on coal usage and reductions of at least 60% on boiler fan electricity consumption.
Boiler Combustion Technology claims significant operational cost savings on coal-fired boilers using its PLC-based solution
Doing away with conventional control methodologies, the company is using modern electronic control technology to make every bit of coal count, to save valuable energy resources and reduce harmful emissions into the atmosphere. Driving the entire combustion process is a Rexroth Bosch L20 PLC in conjunction with a VCP05 HMI, which is used to adjust control variables for different boiler requirements.
The system provides accurate combustion control and interactive boiler operation, allowing the operator to change critical variables such as coal density and chemical composition. The system offers visualisation of the length of the fire on the stoker, which assists the operator when setting the under-grate dampers and the guillotine. Where clients require full automation, the system can also automate the guillotine setting.
