Coke Strength after Reaction (CSR) refers to coke "hot" strength, generally a quality reference in a simulated reaction condition in an industrial blast furnace. The test is based on a procedure developed by Nippon Steel Corp in the 1970s as an attempt to get an indication of coke performance and is used widely throughout the world since then.
For law-enforcement-grade pepper spray, values from 500,000 up to 5 million SHU have been reported, [1] [13] but the actual strength of the spray depends on the dilution. [3] This problem can be overcome by stating the water content along with the Scoville value. One way to do so is the "D-value", defined as total mass divided by dry mass. [14]
Carbon monoxide is not usually supplied as is, in the gaseous phase, in the reactor, but rather it is formed in high temperature in presence of oxygen-carrying ore, or a carboniferous agent such as coke, and high temperature. The blast furnace process is a typical example of a process of reduction of metal from ore with carbon monoxide.
These were the invention of the hot blast in iron-smelting and the introduction of the beehive coke oven. The use of a blast of hot air, instead of cold air, in the smelting furnace was first introduced by Neilson in Scotland in 1828. [9] The hearth process of making coke from coal is a very lengthy process. [citation needed]
