Morison Suspension furnace
The Morison Suspension Furnace was designed and patented by Mr. Donald B. Morison, of West Hartlepool, as the result of a series of experiments conducted at Leeds under the auspices of Mr. Samson Fox. The Fox Corrugated Furnace had been a major advance in boiler design and construction. When the Morison Suspension Furnace was developed it assumed equal rank with the Fox furnace. These two designs were still unrivalled in 1898 despite, during the previous decade, numerous attempts made to produce a viable competitor.
In 1912 Donald Morison was a member of the Council of the Institution of Mechanical Engineers.
