Low-carbon solution for Trelleborg

Trelleborg Wheel Systems is a global supplier of tyres and complete wheels, having one of its facilities in Sri Lanka. Addressing the customer’s need of switching from fossil fuel to biofuels – to reduce their plant’s environmental footprint as well as improve production efficiency – Thermax’s Heating division commissioned a 12 TPH Combipac boiler with a reciprocating grate combustor on a turnkey basis. 

The unit is designed to fire rubber wood chips with high moisture content, a byproduct of their production process, available abundantly. At its full capacity under standard operating conditions, the boiler will use nearly 2,700 kg/hour of feedstock, equivalent to 830 litres of diesel, for generating 12,000 kg/ hour of steam, which is equal to 7.5 MW of effective heat delivered to the process. 

Use of biomass in place of fossil fuel such as diesel will result in a reduction of 15,000 tons of CO2 emissions per year.

 Speaking on the project, Paolo Pompei, President of Trelleborg Wheel Systems quoted in Biomass magazine, an international trade journal, “This is a key milestone project in achieving a reduction in the carbon footprint within the whole organisation—something where we have put huge investment.” He further added, “Energy is a ‘significant element’ in manufacturing costs, and the new boiler and wood chips as fuel will bring a ‘significant reduction’ to the cost of steam generation.”

Getting on the wheels of sustainability

To reduce its dependence on coal while retaining efficiency, Goodyear South Asia Pvt. Ltd., a leading tyre company, reached out to Thermax for adopting sustainable heating solutions. The Heating business commissioned a 28 TPH Bi-Drum reciprocating grate boiler at its tyre manufacturing unit located in Waluj, Aurangabad. Capable of providing uninterrupted operation even on highly choking fuels, the boiler is designed to run on soya briquettes, biomass pellets as well as Indonesian coal to supply high steam pressure of 25 kg/cm2 for moulding, cleaning and drying of rubbers. 

The project was completed on an EPC basis where apart from the boiler, material handling systems for fuel, dry ash and fly ash; ESP and chimney were also supplied, installed and commissioned by Thermax. The project was handed over to the customer for continuous operation within ten months.
