本發明關於燃燒裝置，其具備：燃燒筐、在燃燒筐內並排設置的複數個噴燃器。The present invention relates to a combustion device including a combustion basket and a plurality of burners arranged side by side in the combustion basket.

以往，這種燃燒裝置，具備：氣體分歧部，其以噴燃器的並排設置方向為橫方向，以各噴燃器之混合管部之流入口的開口方向為前方，使朝向各噴燃器之混合管部之流入口來從前方噴射燃料氣體的噴嘴突出設置；以及通氣調節板，其配置在氣體分歧部的後方，具有面對各噴燃器之混合管部之流入口且供燃料氣體及一次空氣通過的開口部(例如參照專利文獻1)。Conventionally, such a combustion device includes a gas branching portion which is directed toward each burner with the direction in which the burners are arranged side by side as the lateral direction and the opening direction of the inlet of the mixing pipe portion of each burner as the front. an inflow port of the mixing pipe portion to protrude from a nozzle for injecting fuel gas from the front; and a ventilation adjustment plate, which is arranged behind the gas branch portion, has an inflow port facing the mixing pipe portion of each burner, and supplies fuel gas and an opening through which primary air passes (for example, refer to Patent Document 1).

[發明所欲解決之問題][Problems to be Solved by Invention]

但是，為了使燃料氣體與一次空氣穩定地流入至噴燃器之混合管部的流入口，是對於通氣調節板的開口部以既定的位置關係來設置氣體分歧部的噴嘴，亦即，有必要正確地確保通氣調節板與氣體分歧部的位置關係。但是，如上述先前例，是個別地將通氣調節板與氣體分歧部連結於燃燒筐，故會因通氣調節板對燃燒筐的安裝公差或氣體分歧部的安裝公差，而難以正確地確保通氣調節板與氣體分歧部的位置關係。However, in order to stably flow the fuel gas and the primary air into the inflow port of the mixing pipe portion of the burner, it is necessary to provide the nozzle of the gas branch with a predetermined positional relationship with respect to the opening of the breather plate, that is, it is necessary to Correctly ensure the positional relationship between the ventilation adjustment plate and the gas branch. However, as in the above-mentioned conventional example, since the ventilation adjustment plate and the gas branch portion are individually connected to the combustion basket, it is difficult to accurately ensure the ventilation adjustment due to the installation tolerance of the ventilation adjustment plate to the combustion basket or the installation tolerance of the gas branch portion. The positional relationship between the plate and the gas branch.
