石油焚小型ボイラーにおける低NO_x対策

抄録

This paper describes the production of NO_x by oil burning and the method of decreasing NO_x.
Tokyo Metropolis enforced the recognition system to NO_x apparatus.-commercial boilers, generating low NO_x, that is lower than 80ppm (O₂=0%) for oil burning.
The concentration of NO_x is influenced by a kind of fuel, the structure of boilers and burners.
Now most of boilers are need the countermeasure of low NO_x.There are three method of decreasing NO_x in small boilers.
(1) Recircuration of combustion waste gas.
(2) Burner with water spray.
(3) Self recircuration burner.
