- Abstract
Victorian brown coal briquettes are a high-volatile fuel of relatively large and uniform sizing and with a very low ash content (about 1.8 per cent). These factors have required modifications to be made to standard industrial coal-firing and handling equipment to make it suitable for briquettes. Special operating procedures have been developed to ensure efficient combustion and to minimise maintenance, particularly of grate components and furnace refractory. These special· designs and procedures are described in the paper together with details of the investigational work which led to them.
A large number of boiler efficiency tests, both short and long term, and other special tests have been made on industrial boilers under normal operating conditions. The results of these tests are summarised and the various design factors influencing efficiency and maintenance are discussed.
Details are given of briquette-fired equipment developed for specialised applications. This equipment includes clay dryers, metallurgical furnaces, automatic steam generators and hot water boilers. Procedures for top firing of continuous brick kilns with crushed briquettes have also been perfected.
The discussion of various aspects related to briquettes may be applicable to other solid fuels, particularly those with low ash content. The discussion of industrial boiler plant design and operation will generally be applicable to any solid fuel and, to some extent, to liquid and gaseous fuels also.
