Blast Tips are small burners designed to handle combustible mixtures of gas and air under sufficient pressure to cause a blast-like flame. In general, Blast Tips are built to burn without the use of any refractory tunnel and are either self-piloting or built to prevent the flame from blowing away under normal conditions of operation. Blast Tips are suitable for a variety of applications. They can be used in groups to heat a wide area such as the bottom of a kettle, or can be mounted down a length of pipe as in a core oven.
