UK: Helvellyn Group, a manufacturer of high energy, low impact solid fuels, has announced the official launch of its cement industry direct coal replacement product in Europe.

Helvellyn has chosen the Global Cemfuels Conference (Paphos, Cyprus 19 - 20 February 2020) as the location for the launch and will be sponsoring the event as well as attending in person.

Helvellyn solid fuels are designed to meet the needs of hard to adapt large industrial plants that are seeking to reduce, or even eliminate, their reliance on coal. The fuels are manufactured to replicate the physical and combustion properties of coal, while reducing the greenhouse gas emissions associated with mining, transporting and burning fossil fuels.

This latest renewable coal replacement fuel has been developed to address the specific needs of cement producers, many of whom have already introduced alternative fuels but are now struggling to increase the ratio due to physical, chemical and technical constraints.

Helvellyn’s product allows operators to maintain their existing alternative fuel mix while, in most instances, adding Helvellyn fuel as a direct drop-in replacement for coal from the point of delivery through pre-combustion processing and in combustion.

The Helvellyn fuel for cement production is based on four core principals, high energy, low moisture, low chlorine and ease of handling. While exact fuel specification and presentation can be fine-tuned to meet the specific needs of a given plant, fuel is typically presented as 50mm hard, hydrophobic lumps with the following properties: energy >25kJ/kg (10,750btu/lb, 5.97kcal/kg); ash content <6%; moisture <2%; chlorine <0.07%; carbon >60%; sulphur <0.2%; nitrogen <0.4%.

Frank Harris, CEO of Helvellyn Group, said, “We are delighted to be launching this important product at the Global Cemfuels Conference 2020. The cement industry has shown innovation and leadership in utilising alternative fuels and we believe we can help them to meet the challenges of the next decade as they further reduce the environmental impact of their product. We are excited to meet with the industry and let it see our fuel for the very first time - it is like nothing they will have seen before.”

Poland: Awbud has signed a deal worth Euro2.85m with LafargeHolcim to build an alternative fuel warehouse and an office building. The deal follows another agreement signed between the companies for an ash-separation installation at Elektrownia Siekierki power station, in which LafargeHolcim has a 30% stake.

India: Singareni Collieries Company Limited (SCCL) has decided to cut coal supplies to the cement industry as it prioritises thermal power plants in Telangana and Andhra Pradesh. Power companies in the two states use 66% of coal produced by SCCL. However, the plants have been unable to work to their full capacity in the second half of 2014 due to a shortage of coal, according to SCCL General Manager S Chandrasekhar.

The decease in coal supplies to the cement producers is expected to make prices rise. Local media reports that the coal from SCCL is more suitable for cement production than power generation as it has a high ash content of 35 – 40%. SCCL is also reported to have encountered several instances of 'misuse' of allocated coal by cement companies. 160,000t/day or 16% of the total coal production is currently allocated to the cement industry and another 6.6% is allocated to captive power plants run by cement companies.
