Vessel Preheating Systems

Vessel /AOD/Convertor Preheaters are special type of preheaters and dryers for very tall (up to 9 mtr in length) vessels .convertor etc. These are used for drying and heating of various types of vessel , These are used to dry and heat the, the burners for these type of preheaters have a long and very intense flame , ensuring a high heat transfer from the flame to the refractory lining , ensuring that the ladle is fully soaked.
We are offering the following additional enhancement:-

1. Recuperative Type Preheater: flue gases exhaust from the ladle at a very high temperature ( 1000 C and above), We use the heat from flue gasses to preheat the air by using a customised heat exchanger specially designed for Ladle applications and are able to save up to 25% in the running cost.

2. Oxy Enrichment: Oxy enrichment is used either to achieve higher heating temperature more than 1200 C or to reduce the fuel consumption or reduce the cycle time. The energy saving can vary from 10 to 25% depending upon the level of enrichment.

3. Multi Fuel Fired: All the burners are custom designed and are for specific requirement and as such we can use multiple type of fuel in the same burner (liquid/Gaseous) without changing the burner, we also supply burners which can fire multiple gaseous.

These systems can be energized by almost all Liquid and Gaseous fuel. We are supplying systems which are using blast furnace gas (800 Kcal/Nm3)

We can offer various type of hood movement for the systems:-

  • Up & down movement using hydraulic or electrical actuator
  • Swivel movement, manually or using an electrical motor.

We offer various working options for the systems

  • Auto Ignition
  • Auto Temperature control
  • PID, PPID Or PLC Based controllers.

We offer your highly customised solutions according to your needs.
