Energy-saving operation management and New technology for Energy-saving. Focus on six new energy saving technologies include: Insulated head cover of Yankee, Revaporation from Hood exhaust, Steel Yankee Dryer, ViscoNip Press, Large Dia. Suction Press Roll, PU cover of SPR. It found: Chinese tissue market’s short-term excess capacity, quality homogenisation, cost-decreasing pressure. In tissue cost structure, energy consumption accounts for manufacturing costs (excelling raw materials) around 70%, around 20% of total costs. Energy-saving design project: tissue line tailored, planning grades, choosing suitable machine configuration with fit speed, capacity and ancillary equipment. Process design shortening and optimising, cutting low-efficiency process. Energy-saving operation management: - Improving efficiency, cutting production cost - Automatic roll changing system, using ceramic blade - Improving rewinding/converting efficiency - Slitting and core shaft system, no rewinding - Increasing Headbox stock consistency, saving electrical consumption - Dewatering optimisation of tissue machine forming and pressings section - Fabrics optimisation for tissue production - New technology for energy-saving:
- Insulated head cover of Yankee - Revaporation from Hood exhaust - Steel Yankee dryer - ViscoNip Press - Large dia. suction press roll - PU cover of SPR Insulated head cover of Yankee: Normally the temperature at open header cover of Yankee dryer is around 150 degrees celcius, so energy lost of heat radiation is high. Utilisation of insulated head cover can save 2.5%-5% of steam consumption. Advantage of Visconip press: Possible tissue dryness would be increased 7% by increasing peak pressure up to 4.5MPa, this dryness increase corresponds to a drying energy saving 25%. Gives a bulk increase of around 10% compared to suction pressure roll and improves softness.
Economic impact of greenhouse gas emissions regulations; Stanley Okoro, general manager, Fisher International, USA Globally, T&T production emits more carbon per tonne of paper than any other grade. What’s more, coal burning power plants in China and Indonesia have the highest CO2 emission factors. With the potential to alter the competitive position of individual mills, the carbon issue is becoming increasingly
