in This article, we are describing how steam turbines are used in the paper
industry to generate their own power at a reduced cost which is up to Rs. 1
to Rs.2 per unit. firstly we will know how Turtle Turbines work in the paper
industry, their principles of operation, and which types of steam turbines
can be utilized in the paper industry to provide more power for less money.
Steam turbines are proving themselves very effectively in the Pulp & Paper industry.
they provide the Process Heat and Power. Steam turbine inlet
steam conditions are typically between 12 (barg) Dry and Saturated and 63
(barg) 480 (°C). The Steam is fed to the Steam Turbine to generate power.
Exhaust steam from the Turbine is used in the process of heating.
There is a cost to creating steam at process pressure rather than high
pressure to generate electricity at the top end. Cogeneration, on the other
hand, has a lost opportunity cost since steam. it still retains a significant
amount of enthalpy that may be utilized for power generation under normal
process heating conditions. The high cost of grid power has a direct impact
on the bottom line of the paper industry. manufacturers’ best alternative
is to build their own captive power plants that will run in cogeneration
mode. High-pressure boilers, turbines, and generators have high capital
and operational costs, and they are normally operated constantly, limiting
self-generated power to large-scale activities.
Extraction pressures of 11 kg/cm2 and 4 kg/cm2 may be found in a typical
power generation turbine in a paper mill. The average backpressure is
around 4 kg/cm2. In reality, these pressures are tailored to the specific
needs of each site. It’s used to separate fibers and soften pulp during the
pulping process, as well as bleaching and mixing oxygen into the pulp
