Specialist Dust Control Solution Protects Workers During Shutdown Maintenance at Kent Enviropower.

Case Study Overview

FCC Environment is a waste and resource management company which looks to deliver change for a sustainable future. They are committed to reducing the UK’s reliance on fossil fuels, and currently have seven Energy-from-Waste facilities nationwide. One of the facilities is Kent Enviropower, based in Maidstone, Kent.

The main purpose of the Maidstone site is to recover energy from non-hazardous waste, processing up to 550,000 tonnes of mixed waste a year. With such a positive impact on reducing fossil fuel use, and supplying many homes with power, keeping the site working efficiently is vital.

The facility uses two large furnaces to turn waste-to-energy. To ensure these work as efficiently as possible throughout the year, there are two scheduled shutdowns a year, which is when any maintenance or repairs to the furnaces take place. With such a reliance within the local area, one furnace is shut down at a time, and there are very tight deadlines to meet. Any delays can cost thousands of pounds.

Challenge

It was identified that dust control was imperative for the project to go ahead safely. The main work scope included extensive removal of the refractory lining, and re-lining works to be carried out, all of which would create hazardous dust. Due to the nature of what the furnaces do, the works needing to be done were within confined spaces, with no access to fresh air. Dust control was paramount in the protection of workers health and the environment they were working in.

FCC Environment reached out to the RVT Group following previous success of working together to control hazards on site. One of RVT’s technical consultants visited the site to better understand the challenges, and to recommend an effective dust control solution.

Solution

RVT Group implemented specialist dust control solutions on levels 3 and 5 of the furnace to protect workers from dust exposure, and to reduce potential visibility issues that could be caused by airborne dust within the confined space. Across both levels, we installed a combination of solutions which consisted of DUSTEX® Superfilta 40, VENTEX® Centrifugal Fan 200S-HP and RAVEX® Wandafilta Plus.

Following the implementation of our equipment across the two levels, we successfully extracted high volumes of dust from the work areas, helping to create a safe environment for workers, and protect them from any long-term health conditions.
