The furnace most commonly used is a continuous regenerative furnace capable of producing between 45 and 272 megagrams mg 50 and 300 tons of glass per day. Knowing the sequence of operation of a gas furnace will save time and money on troubleshooting calls.
Figure 11 15 2 is a flow diagram of a typical batch plant. Process flow diagram for blast furnace. The flame sensor will attempt to detect the flame source if there is a working flame source it will allow gas to flow and light it if not it will keep the gas off.
A furnace may have either side or end ports that connect brick checkers to the inside of the melter. If you have a gas valve that has a pv pilot valve and an mv main valve then i would think that either you are not getting the 24 volts to the pv since the pilot is not lighting to continue the furnace ignition sequence. This article includes a diagram of furnaces with different air flows and an explanation of when different configurations are appropriate.
