Magadi

The rising costs of energy coupled with a growing concern for environmental conservation call for attention to further improvements in the way we use energy within our business operations. Energy efficiency and conservation strategy is a priority if our products and services are to remain competitive. Here are some of our energy and cost-saving measures.

Replacement of Rotary Kiln Refractories

Heating equipment, such as furnaces, can experience significant radiation losses when operating at temperatures above 1,000°F. Therefore, the repair of the calciner walls was necessary to reduce such losses.  This enabled the company to make a saving of 47,047KG of HFO Annually.

Further to improve fuel efficiency we are procuring latest design hot gas generator system for Kiln at the cost of 75 million Kenyan shilling. This will improve fuel burning system and will bring saving of 5% of fuel consumption for each kiln.

Process Integration

Process integration is a holistic approach to process design and operation that emphasizes the unity of the process. The company installed a SCADA that measures parameters such as the moisture content, final ash temperature, fuel temperature and furnace wall temperature to ensure that they are at sync with each other and minimize energy loss.

LED Retrofits

The company has replaced more than 100-250W tungsten lamps with 100 LED lamps. There is also an ongoing initiative to replace all 58W fluorescent tubes with 22W LED tubes. TCML no longer procures tungsten lamps and fluorescent tubes.

Reduce Pressure Loss in Compressed Air System

There was a 1.7 bar pressure loss between the compressor and the final air receiver. This was caused by the long distance between the compressor and the receiver. To minimize energy loss, the company replaced the 110KW compressor with a more energy efficient 75KW system. The compressor was also installed next to the receiver.

Undertaken an on-spot measurement of NOx and SOx in November to help understand impacts. We are monitoring the quality of every batch of fuel. Now, we are have changed the type of boilers from diesel to electric. Magadi is focusing at a grand scale on carbon sequestration.

TCML has developed tree planting project as an initiative of water conservation in the catchment areas of loita hills, where the river supplying Magadi with water originates. There have been several types of trees planted within the area to increase tree cover. This exercise targets to reduce flow fluctuations in rivers, hence a constant supply through the year.
