calorific value
Thread Content
Among various types of biomass, straw, rice husks, and sawdust are commonly used in biomass gasifiers. I have a question: what are the calorific values of wheat straw, rice husk, and sawdust respectively?
I remember answering your question about the density and calorific value of rice husks last time. The data I have available is for reference only: Rice husks: 15223 kJ/kg; Wood chips: 18112.5 kJ/kg; Straw: 14499 kJ/kg
From what I understand, straws seem to have a higher calorific value than rice husks
The energy released upon the complete combustion of 1 kg of solid (liquid) fuel or 1 m3 of gaseous fuel is referred to as the calorific heat or heat value of the fuel. Considering the state of water in the fuel combustion products, the calorific value that includes the latent heat of vaporization of water is referred to as the high heat value or high calorific value (HHV) ； The calorific value that does not include the latent heat of vaporization of water vapor is called the low heat value or lower heating value (LHV).
The lower calorific value is used as the basis for thermal calculations in boilers. Coal with a lower heating value of Qnet,v = 29308 kJ/kg (7000 kcal/kg) is referred to as standard coal.
Depending on the source of different raw materials, the components of wheat straw and rice husk vary in different regions. By the way, what I listed are straw strands; they should be rice straw, not wheat straw.
Hello, I’m glad you’re able to provide useful information, but please read the question carefully before giving your answer.
