45 results about "Smouldering" patented technology

Smouldering (British English) or smoldering (American English; see spelling differences) is the slow, low-temperature, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface of a condensed-phase fuel. Many solid materials can sustain a smouldering reaction, including coal, cellulose, wood, cotton, tobacco, cannabis, peat, plant litter, humus, synthetic foams, charring polymers including polyurethane foam and some types of dust. Common examples of smouldering phenomena are the initiation of residential fires on upholstered furniture by weak heat sources (e.g., a cigarette, a short-circuited wire), and the persistent combustion of biomass behind the flaming front of wildfires.

Method for coke dry quenching by coal internal heat smouldering

The invention discloses a method coke dry quenching by coal internal heat smouldering. In the method, high temperature carbonized coal gas produced by carbonized dry quenched coke is made into cool coal gas by washing and collecting tar; after the cool coal gas passes a circulating fan, part of the coal gas is introduced into a burner to be synthesized with high temperature waste gas into high temperature mixed gas satisfying the coal smouldering requirement; the high temperature mixed gas enters into a carbonization section of a coke oven to be used as a carbonization heat source; the other part of pure coal gas passing the circulating fan is introduced to a coke quenching and cooling section of a carbonization furnace by a booster fan to be used as an inertia medium of Ramsbottom coke and quenched coke; the cool coal gas passing the coke quenching and cooling section of the carbonization furnace absorbs the heat and then passes the carbonization section of the coke oven to carry out nonoxidation heating or weak-oxidation heating towards the coal together with the carbonization heat source to realize combustion-free circulation. The method simplifies the coke dry quenching technology, reduces the water content of the Ramsbottom coke, uses the heat of the Ramsbottom coke before coke quenching effectively, improves the utilization rate of the pure coal gas, reduces the use of combustion-supporting gas and accordingly reduces the energy consumption of the burner.
