The millions of litres of water used for processing purposes are taken from the Lièvre River. Once used, the water is returned cleaner than it was when drawn out. To see how this is done, please click “Continue” below.

Steam Plant

Mission

To ensure the uninterrupted availability of steam while complying with environmental and safety standards.

Description

Steam is produced using 2 VU Combustion Engineering boilers built in 1941. Over the years, these boilers have been upgraded from pulverized coal as a combustible fuel, to heavy fuel oil or natural gas. Eight Peabody APR 19 Venturi burners allow us to produce, using either fuel oil or natural gas, 120,000 kg of saturated steam per hour (265,000 pounds per hour), at a working pressure of 1,100 kPa (160 lb).

Total steam production (with TMP)in 2004 reached 613,624,000 kg. In order to produce the steam required for drying the paper sheet, heating the mill and meeting other equipment needs for steam, we burned the following amounts of combustible fuel:

Heavy fuel oil: 15,557,740 litres
Natural gas:3,646,268 cubic metres

According to Gazifère, a natural gas company, the average annual amount of natural gas consumed in a single-family home in the Outaouais region is approximately 2,000 cubic metres for heating the home and 800 cubic metres for heating water. In 2004, our boiler burned 3,646,268 cubic metres of natural gas, which equates to what would be used by 1,302 homes.

The Operator Interface and the ABB-Bailey distributed control system, with three monitors in all, enable the operators to control the boilers and manage the volume and distribution of steam in response to mill needs.
