Among the figure: 1-coal gas diffusion mouth, 2-shell, 3-supercharging air port, the 4-hermatic door that feeds in raw material, 5-inner bag, the 6-overfiren air port, 7-bocca, 8-fire bars, 9-scarfing cinder hermatic door, 10-primary air nozzle, 11-deashing hermatic door, the dry-type encapsulated chamber of 12-, 13-ability of swimming closed chamber, the combustion chamber takes place in 14-coal gas
The specific embodiment
In conjunction with the accompanying drawings embodiments of the present invention are described further, embodiment is used for illustrating of the present invention, rather than it is imposed any restrictions.
The inner bag 5 that the present invention includes shell 2, is made up of water jacket and flame retardant coating, inner bag 5 inner chambers are that combustion chamber 14 takes place coal gas, and 14 bottoms, combustion chamber take place coal gas is fire bars 8, and fire bars 8 belows are closed chamber.14 tops, combustion chamber take place and establish reinforced hermatic door 4 in coal gas, and have coal gas diffusion mouth 1; 14 bottoms, combustion chamber take place and establish scarfing cinder hermatic door 9 in coal gas.Closed chamber has deashing hermatic door 11.Dry-type encapsulated chamber 12 sidewalls are provided with the deashing hermatic door.The deashing hermatic door is established in ability of swimming closed chamber 13 bottoms.Reinforced hermatic door 4, deashing hermatic door 11, scarfing cinder hermatic door 9, coal gas diffusion mouth 1, can adopt manual or electronic control to rise to close.
