Coke & Bio Coal Moisture


Coke processing requires varying conditions to properly attain the desired outcome. In the drying stage of the process, coke ovens can account for almost 10% of the energy consumption in a plant; proper moisture measurement and control of the material prior to being utilized for energy can majorly decrease the energy usage and increase the efficiency of the production line.

Mainly used for fuel and energy, coke is a solid carbon source used to melt and reduce iron ore. The process of obtaining by-products from coke include oven processing to remove ammonia, light oils, tar, sulfur and phenol before it can be used as a heating source for the ovens.

Precise and accurate measurements of moisture content can provide the ability to immediately regulate or interfere with the production process to correct issues before they arise. With most coke applications there are multiple processes to heat and cool the product and in some instances recycle. For an immediate, repeatable solution to maintain efficiency in production, accurate moisture testing instruments are necessary.

Wet Quenching Method 

The most popular method for coke is the wet quenching method wich assumes spraying water over burning coke in the quenching tower of the process. Once cooled the coke is then screened and prepped for its final process/product. Due to the extreme conditions that can occur when processing coke, MoistTech reccommends the CCS-3000 moisture sensor for optimum results.

The CCS3000 takes accurate measurements of moisture (in % dry and % wet) allowing you to regulate moisture levels either automatically or manually. It also takes measurements of temperature, and other levels vital to coke and coal production.


  • Cut production costs
  • Boosting product quality
  • CCS3000 is low maintenance & energy efficient.
  • Reduce start-up and downtime
  • Eliminates waste due to incorrect moisture content
  • Cleaner, more efficient fuel

Moisture Content in Bio Coal 

Biomass Briquette OR Bio Coal is made from agricultural, wooden and forestry wastes by high compression process without adding any chemical, glue or binder. It is thus ‘binder-less’ technology product resulting in 100% natural eco-friendly, pollution-free solid fuel. Biomass briquettes are a renewable source of energy and avoid adding fossil carbon to the atmosphere. It can provide a similar amount of energy as low-grade fossil coal and 30% – 80% more energy than wood pellets

A popular biomass briquette takes a waste produce such as sawdust, groundnut shells, cotton stalk, castor seed shells etc.; compresses it and then extrudes it to make a reconstituted log that can replace firewood and coal. A very low moisture and ash content around 8% makes briquette preferable solid fuel. Briquettes give much higher boiler efficiency because of low moisture and higher density; since bio-coal has high density, it saves transport costs and space in storage.
