Central to the production of natural soda ash is one thermal processing device: the rotary calciner. Soda Ash Production. Historically, soda ash was manufactured via the Solvay process, a series of chemical reactions utilizing sodium chloride, ammonia, and …
The price of a limestone product is largely governed by the cost of extraction, processing and transportation. The high capital costs of quarrying, due to the high investment in machinery to work and process the stone, has led to the development of large quarries that can produce high tonnages over long periods of time.
Fuel is injected into the bed of the calciner zone by means of a number of injectors to raise the temperature to that required for calcination. For coal firing, a pre screened coal of 1 mm x 4 mm is injected along with the limestone into the calciner freeboard.

The kinetic parameters were used to predict limestone conversions in an ideal flash calciner and in SAP. Ideal flash calciner assumed isothermal condition throughout the reactor while the later one used the actual temperature profiles in SAP to predict limestone conversion at different CO2 partial pressures.
Technological measures such as finer grinding, pre-calciners designed to have a higher retention time, an external combustion chamber before the calciner, a special high-momentum kiln burner, etc. will help to effectively utilize Petroleum coke. Based on the quality of Petroleum coke, typically a mixed fuel firing is designed.
Optionally, the second- or third-lowest stage cyclone material can be further split to allow for diversion of a portion of the meal directly into the upper section of the calciner. This creates a “hot zone” in the lower section of the calciner that boosts the burning of difficult fuels and further NO x reduction.
Balanced Energy Networks Carbon Negative Calciners . A fuel cell calciner can be used to generate electricity in a combustion-free process that converts limestone into lime and yields pure CO 2 which can be sequestered geologically without the …

Figure 4 shows the limestone mass fraction in particles and their distribution inside the calciner for the three calculated co-firing cases. As can be observed, limestone mass fraction decreases from the calciner’s inlet towards the outlet, and in all three cases the position of limestone particles is similar.
