Abstract
Method of heating glass contacting surfaces, comprising heating the glass contacting surfaces to a predetermined operating temperature by combustion of a hydrocarbon fuel gas mixture which includes 90% by volume of MAPP gas and 10 percent by volume of propane. Another method blends the MAPP with air and/or natural gas. A novel hydrocarbon fuel gas mixture which includes 90% by volume of MAPP gas and 10% by volume of propane.
Claims20
A method of heating glass contacting surfaces, comprising the steps of:
- heating said glass contacting surfaces to a predetermined operating temperature;
- said heating of said glass contacting surfaces is accomplished by combustion of a predetermined gas in a flame;
- and
- said predetermined gas comprises a hydrocarbon fuel gas mixture which includes approximately 90 percent by volume of MAPP gas.
A hydrocarbon fuel gas mixture especially suited for heating glass contacting surfaces and/or lubricating purposes, comprising:
- a hydrocarbon fuel gas mixture which includes approximately 90 percent by volume of MAPP gas.
A method of heating glass contacting surfaces, comprising the steps of:
- heating said glass contacting surfaces to a predetermined operating temperature;
- said heating of said glass contacting surfaces is accomplished by combustion of a predetermined gas in a flame;
- said heating of said glass contacting surfaces is started with a 100% mixture of MAPP gas to limit carbon skeleton formation;
- then there is introduced a small quantity of natural gas which has extra hydrogen atoms to give a suppressive influence for carbon formation;
- and
- said heating of said glass contacting surfaces is maintained to avoid any chance of dirty glass contacting surfaces.
A method of heating glass contacting surfaces, comprising the steps of:
- heating said glass contacting surfaces to a predetermined operating temperature;
- said heating of said glass contacting surfaces is accomplished by combustion of a predetermined gas in a flame;
- said heating of said glass contacting surfaces is started with a 100% mixture of MAPP gas to limit carbon skeleton formation;
- then said MAPP gas is mixed with air to produce a heat transfer system which will maintain a sustained temperature on the average of 1800 K;
- and
- said heating of said glass contacting surfaces is maintained to avoid any chance of FO dirty glass contacting surfaces.
