The Canadian Carbonization Research Association and CETC-Ottawa undertook a joint lab/pilot scale program to investigate factors influencing coal dust losses during simulated coal rail transportation from the mines to distant (>1000 km) customers and ports, using a scaled model rail car in a wind tunnel. A final report of CETC-Ottawa's laboratory investigations were presented to CCRA. This paper highlights some of the tests undertaken in this study and discusses their relevance to industrial coal transport in British Columbia. The results of comparing the impact of different crusting agents agreed with the relative order found by industry earlier. Detailed studies were undertaken to evaluate the use of five different crusting agents and the results indicated that an anionic polymer and latex were the most effective. Coal profiles have a major impact on coal dust losses even when treated with coal crusting agents. Reduction of sloping cavities from the coal profile is important, particularly the size of the sloping profile at the rear of the coal car. Reversing the train would reduce dust losses by having the larger sloped area at the front of the car. Re-spraying of damaged coal crusts was the most effective method to reduce coal dust emissions.
