Set the boundary first. Collect site evidence before selecting a measure or reporting a result.
Separate melting, forming, annealing, batch preparation, cullet handling and utilities. Record the glass product and furnace type.
Batch and cullet composition, fuel and electricity, furnace pull, temperatures, exhaust conditions, product yield and operating campaign.
Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.
Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.
Assess furnace changes at the appropriate rebuild point. Keep batch changes, combustion changes, electricity and utility measures separate.
Review forehearth, lehr, hot-air, steam and hot-water services. Furnace refractory and crown work require specialist furnace engineering.
