| 摘要 |
A combustion-heating system includes a plurality of combustion heaters connected to each other, a combustion heater including: a heating plate; an arrangement plate; an annular outer peripheral wall; a partition plate; a combustion chamber in which fuel gas collides with a flame-holding part constituting part of the outer peripheral wall, and thereby holding flames; an inflow path through which the fuel gas flows into the combustion chamber; and an outflow path through which exhaust gas flows from the combustion chamber toward the outside thereof, the outflow path to preheat the fuel gas by heat of the exhaust gas through the partition plate. The combustion-heating system includes a communication path communicating combustion chambers thereof with each other. The flame-holding part and the communication path are provided in series in a direction in which the heating plate and the arrangement plate face to each other.
