KOELLEMANN preheaters are used to heat up petroleum coke. Petroleum coke is a residue formed as a by-product of petroleum refining and is made of almost pure carbon. KOELLEMANN Petroleum coke Preheaters are responsible for the heating process, which involves heating the petcoke from a minimum of 0°C to around 200°C. An electric mixer kneads the heated petroleum coke and hot pitch together until a paste is created, which is then shaped into blocks. KOELLEMANN provided Petroleum coke Preheaters distinguish themselves from other items accessible on the global market due to their state-of-the-art construction. KOELLEMANN design provides significant benefits in terms of maintenance, longevity, efficiency, and the amount of space needed. By applying the hollow flight principle our Petroleum coke preheaters offer maximum performance within the smallest possible space.
Modular design out outer insulation
Minimizing the heat losses at high temperature heating medium
Maximizing the serviceability by easy dismountable insulation covers
Especially developed carbon bearings, with the smallest possible maintenance work and costs.
Throughput rate up to 60 t/h (currently, might be increased later)
Product temperatures up to 220°C
Modular insulation
The entire unit is placed on a solid frame, no individual foundations
The modular insulation is on one side maintenance friendly due to rapidly removable panels
and insures on the other side by minimizing radiation losses best possible exploitation of the supplied heat.
The challenge mastered by extensive development is compensation of the thermal expansion of the worm shaft, which is completely absorbed by the especially developed KOELLEMANN carbon bearings, with the smallest possible maintenance work and costs. The tongue-shaped shaft passages enable individual worm shafts to be replaced easily without dismantling the end wall or the other shafts. This minimizes downtime significantly.
