Pulverized coal burner fired with dense-phase turbulence

摘要

burner for coal dust when combusted with zawirowaniem in dense phase contains the main air channel (1), the auxiliary air flow (2) and an external direct channel auxiliary air vortex flow (3),with along the housing working oil (4) in the straight section of the main air pipe (1) there are many equally spaced levels zagu0119szczaju0105cych coal dust rings (6), whereby the stream of mixture of coal dust and air is distributed in g ruby creek outside and inside thin stream nozzle air main.dense phase coal dust air outside the nozzle main flows through the stator blades, where its flow is disturbed, which is placed in a furnace, stirring rapidly and sufficiently at outlet of reverse stream of exhaust gas high temperature.at the same time, stream of coal dust and air mixture rare phase inside is directly placed on the hearth, which ensures the subsequent mixing and combustion of coal dust.the main and auxiliary air nozzle, air nozzle with conical structures extending about a corner which ensure proper mixing controlling auxiliary air and coal dust.
