How much gas and electricity does a Morbi tile unit use for each square metre of tile, and how much carbon dioxide is that?

Question

Accepted Answer

The Bureau of Energy Efficiency (BEE) Morbi manual prints 1.51 to 2.11 standard cubic metres (scm) of gas and 3.71 to 5.01 kilowatt hours (kWh) of electricity for each square metre of vitrified tile, and 1.28 to 1.8 scm and 1.51 to 1.92 kWh for wall and floor tile. A standard cubic metre (scm) is the amount of gas that fills a box one metre long, one metre wide and one metre high, measured at a fixed standard temperature and pressure so that every bill counts the same way. Your gas bill shows it. A kilowatt hour (kWh) is one unit on your electricity bill. Carbon dioxide is the gas that leaves a chimney whenever fuel is burnt, and the one buyers ask you to count. Gas and power are counted differently, so the page keeps them apart. Vitrified tile, the glass-hard floor tile that is polished after firing: 3.71 to 5.01 kWh and 1.51 to 2.11 scm for each square metre. Wall and floor tile together: 1.51 to 1.92 kWh and 1.28 to 1.8 scm for each square metre. Sanitary ware, counted by the tonne: 57 to 128 kWh and 81.48 to 110 scm for each tonne. The manual says the figures come from data the units gave, and that solid fuel is converted to the gas it would equal. My reading: the gas column therefore covers spray dryer and dryer heat, not only the kiln. Multiply gas by the factor for piped natural gas, 2.05 kilograms of carbon dioxide for each scm, and electricity by 0.675 kilograms for each kWh (the grid factor for financial year (FY) 2025-26). The two columns then add. The low ends are added to each other and so are the high ends, so each total is a band, not a promise for any one unit. The gas factor only fits gas. If your spray dryer burns lignite or coal, the manual's gas-equivalent column hides that, and 2.05 is the wrong factor for the solid fuel share. Use your own fuel invoices for that part. The same study's polishing report says kiln gas alone runs 1.01 to 1.4 scm for each square metre of tile. That is lower than the 1.28 to 1.8 above for wall and floor tile. The manual does not say why, or which tile type the kiln-only range is for; set against the vitrified range of 1.51 to 2.11 it is also lower. My reading, not the manual's, is that the larger table also counts the spray dryer and the dryer. Quote the one that matches the meter you have. These are 2009 to 2010 audit figures. Kilns, burners and fuel mix have changed since. Use the ranges to sense-check your own bills. A figure far outside the range is a reason to look at the meters, not proof of an error. Divide by square metres packed and sold, not square metres pressed.
