Kattameya plant burns biomass for the first time

11 April 2019, Published under Cement News

The Suez Cement Kattameya plant (HeidelbergCement Group) has used waste as alternative fuel (AF) in its main burner for the first time this week. The Kattameya plant’s team successfully burnt waste as an AF in the main kiln burner and reduced dependence on fossil fuel by around 10 per cent of the total fuel used. This is in addition to substituting 15 per cent of fuel in the calciner, resulting in a total thermal substitution rate (TSR) of 25 per cent. Therefore, waste and biomass burnt...

Aluminium and iron in clinker

06 February 2019, Published under Cement News

Aluminium and iron are two of the key components in Portland cement clinker. Varying their presence in clinker can have significant effects on the final clinker. Arthur Harrisson looks at some of the impacts of such variations. Figure 1: light grey aluminate and white ferrite very slowly cooled. The hexagonal blue alite crystal below centre is 30µm across The four essential constituents of Portland cement clinker are usually listed as: • calcium oxide (CaO or, in cement chemi...

Cementos Alfa plans doubling biomass use

Cementos Alfa, part of the Portland Valderrivas Group, has avoided the emission of 31,000t of CO 2 at its Mataporquera plant, Cantabria, in 2018 as a result of the use of 150tpd biomass as alternative fuel. Moreover, the use of the fuel, through improved energy efficiency, is enabling the company to remain competitive. In 2019 it plans to double the amount of biomass and therefore, has applied to the Spain’s General Directorate for the Environment to extend the authorisation. Output at t...

FLSmidth to install HOTDISC at Golden Bay cement plant

29 January 2019, Published under Cement News

FLSmdith has won an order from Fletcher Building to install a HOTDISC® combustion device at its Golden Bay cement plant in New Zealand. Local media reported that substituting rubber biofuels for coal will reduce CO 2 emissions by 13,000 tonnes per year, or the equivalent of emissions from 6000 cars. Once the FLSmidth HOTDISC is fully operational, the kiln will consume up to 3.1m shredded tyres a year, replacing the need for over 15,000t of coal. New Zealand’s Associate Minister for th...

Reducing cadmium volatility

19 December 2018, Published under Cement News

A recent news report for the Journal of Engineering described some experimental work that has been carried out in China designed to investigate the behaviour of some heavy metals, especially cadmium, in cement clinker. In particular the work looked at the influence of chalcogens on the volatility of cadmium. The content of cadmium in alternative fuels may be higher than in fossil fuels Chalcogens are a group of elements also known as the oxygen family. It consists of the element...
