A review of all the foregoing test work indicates that solution should be offered to at least three distinct problems. The first problem can be termed a physical and chemical problem, and refers to the reasons for the firebrick reactions under impingement, carbon deposition and carbon penetration between temperatures 2000 F and 2300 F. The second problem can be termed a problem of design, and simply stated refers to a suggested design for a low cost and low maintenance refractory furnace, for an oil fired steam boiler. The third problem is a mechanical engineering problem and refers to the selection of proper firing equipment to suit the particular service, (type of steam demand) for which this equipment will be used. It is felt that a clear view on these three matters should contribute materially to reductions in the cost of operating oil fired boilers, while at the same time increasing their useful life. The test work which has been described raises the physical and chemical problem in a threefold manner as is evident both in the operating tests and in the laboratory tests. [...]
