Preheater and Calciner

A TEC is your specialist in preheater optimization as well as calciner optimization. The core of the pyroprocess of each modern cement kiln is the preheater. Most substantial thermo-chemical reactions of the cement process occur in the riser ducts and in the calciner(s) and certainly in the sintering zone of the kiln.

Preheater and calciner

Preheater and Calciner. RCL has five stages of high-efficiency, low-pressure preheating. RCL's preheater cyclone tower is 108 meters tall. Raw meal is fed from the top of the tower, and it travels from there to the bottom through several cyclones. Each cyclone in the preheater serves as a heat exchanger and a separator.

Calciner

The calciner is where clinker production really starts to get going. It's where preheated raw meal and fuel mix within a hot air stream to begin the calcination reaction – the first step to making clinker.

Preheater

Preheater & Calciner Vessels. Installed upstream of the calciner and the rotary kiln, the preheater is a tower that heats up the raw mix with hot gases from the kiln. Main components of the preheater tower are cyclones which are conical vessels with openings at the top and bottom. Hot gas laden with raw mix is released tangentially inside a ...

Pyroclon® LowNOx AF

Proper mixing of material and gas flows is important to ensure complete combustion. Which is why we developed the Pyrotop ® mixing chamber. Fitted to all KHD calciners, it enhances mixing at the gas turning point at the top of the calciner to ensure combustion is complete before the gas stream enters the lowest cyclone stage of the preheater.

Gas flow optimization for Top Cyclone Preheater …

rotary kiln, a cyclone preheater (suspension preheater), and a calciner. Cyclone Preheater is the core equipment for cement production using kiln dry process technology. In this process, a raw mix with low water content (e.g., 0.5%) is used, to reduce the need for evaporation and reduce the length of the kiln.

Reducing Heat Consumption in Preheater and Calciner: The …

The preheater preps the raw material by heating it, while the calciner is responsible for the early stages of clinker formation, where raw material gets exposed to very high temperatures. These two units consume a large portion of the plant's total energy, so improving their efficiency is key to reducing overall heat consumption.
