A professional who tends series of burners, located in channel-process burner buildings (hot houses), that produce carbon black by contact of gas flame with collecting channels, from which deposited carbon is scraped. Respnsibilities include:

• Turns valves to regulate flow of gas or mixture of gas and oil to burners to produce flames that deposit carbon black on channels (flat surfaces).
• Turns handwheel to bring channels into contact with flame.
• Opens and closes doors at sides and ends of burner building to regulate draft and compensate for changes in atmospheric conditions, air-fuel mixtures, draft, and fuel consumption.
• Observes, through building ports, accumulation of carbon black, automatic scraping of accumulation from channel, and flow of carbon black through conveyors to detect malfunction of burners and scrapers and to verify production rate.
