We are revolutionizing the efficiency of global blast furnaces. Bionic innovation from the heart of Romania.
Stove Logic presents the new generation of regenerators for air preheaters (cowpere). Technology inspired by nature (marine sponges) for maximum heat transfer, guaranteed vortex and reduced operational costs.
The Problem - The 1860 Design
For over a century and a half, air preheaters have operated on a strictly vertical gas circulation principle. This approach generates major thermal inefficiencies: uncontrolled turbulence in the dome and, most seriously, the formation of a thin layer of insulating gas on the walls of the channels, which blocks optimal heat transfer to the refractory material.
The Solution - Stove Logic Innovation
Vortex Guaranteed: Pressure differences force gases to flow through horizontal channels, creating vortices perpendicular to the direction of flow.
Maximum Efficiency: These vortices destroy the insulating layer of gas on the walls, unlocking massive heat transfer.
Unparalleled performance, irrefutable technical data.
Massive increase in the temperature of the hot air injected. Gas vortexing is guaranteed in any vertical channel, making the Reynolds number or the D. Sanna curve irrelevant.
Reducing coke consumption per ton of pig iron. Every 100°C increase automatically reduces the manufacturing cost on the production line.
Increase obtained without altering the porosity of the structure (maintained below 5% variation) and without requiring a change in the refractory mass of current solutions.
Blockage safety:
The interconnected 3D labyrinth cancels out the effects of any local obstruction in a vertical channel, guaranteeing constant technical performance throughout the life of the cowper.
From Galați to world leaders
The foundation of this innovation has been rigorously tested and validated in the field. In the 1990s, in Galați, Romania, the first horizontal channel regenerator was experimented on a 1000 cubic meter blast furnace.
Expertise results (1994): The Metallurgical Research Institute in Bucharest confirmed an increase in technological efficiency of approximately 5.5% and an extra 48°C at the temperature of the hot air blown in, compared to classic models.
Global Adoption: That first solution was taken over worldwide, through contracts with the author, by industrial giants such as USX (US Steel) and Mittal Steel, being patented in the USA, Japan, Mexico and the European Union.
New Stove Logic Patent: The Next Technological Leap
Today, Stove Logic presents the new bionic solution. It is a clear evolution, clearly superior to the previous generation in all aspects of heat transfer and fluid dynamics. We offer precision engineering, supported by computational calculations and accurate 3D models, ready for immediate integration.
