Instant productivity boost with IQ Steam Profiler

The results were seen immediately, the desired improvement in product quality was visible. Our Operators have become so confident about the steam profiler that they don’t want to switch it off.

Direct savings in steam - under 1 year payback time

The Valmet IQ Steam Profiler is a high technology multi-zone steam box providing unique profiling accuracy for the forming and press sections of paper and pulp machines. At Naini Papers, the installation location is on the wire section above the Trivac suction box to heat the sheet by 20° C prior to the press. By heating the water in the sheet, its viscosity is lowered allowing it to drain more readily and reduce moisture entering the pulp dryer.

The advanced steam injection technology employed by the IQ Steam Profiler maximizes steam absorption efficiency and its electromechanical actuators with position feedback provide high-performance profiling capabilities. Dryness after the couch has increased significantly which translates directly to savings in steam consumption.

Mr. Pawan Agarwal, Managing Director of Naini Group, who is well known for his continuous drive to implement the latest available technologies in the mill, says: "The results were seen immediately, the desired improvement in product quality was visible."

"The biggest benefit with IQ Steam Profiler was improved product quality with respect to even moisture profile. Our Operators have become so confident about the steam profiler that they don’t want to switch it off." Mr. Pawan Agarwal further added.

Steam consumption reduced 0.1mt/mt right after the installation of the IQ Steam Profiler.

“We think the steam box technology supplied by Valmet is world-class and well supported by the team Valmet.”

Quality improved to the target level

Higher average dryness provides the room for moisture profile control. Prior to installation, an uneven moisture profile from the press, with one side of the sheet drier than the other, made it difficult to achieve moisture targets at the reel. The IQ Steam Profiler with 40 controlled zones across the sheet has enabled an increase of moisture at the pope reel from 3.2% to 4.2% with a significant improvement in 2 Sigma profile values.

Since the successful summer 2019 startup, mill project objectives and Valmet’s performance guarantees have been met. Savings and quality are both on target with together with more uniform reel buildup and warp-free stacking of cut sheets. Discussions are already underway for another IQ Steam Profiler for Naini’s second machine at Naini Tissues Ltd., which also makes writing and printing paper from agricultural residue, mainly bagasse and wheat straw. Both machines already have Valmet IQ quality management and control systems, which together with the latest investment show Naini Group’s confidence in Valmet, a constructive and profitable partnership for both companies.

“We think the steam box technology supplied by Valmet is world-class and well supported by the team Valmet”, says the production team from Naini Papers.
