Abstract

PURPOSE:To enable a burner to burn constantly at optimum state subject to almost no fluctuation of air flow regardless of external conditions such as exhaust cylinder, air speed etc. by means of utilizing a capacity type blower for a burner. CONSTITUTION:Burning air for a burner is fed from a capacity type blower while the revolution of said blower is controlled corresponding to the fluctuation of fuel to maintain the air fuel ratio. The main purpose of the capacity type blower is to make the blowing capacity almost constant utilizing the constant blowing capacity to be specified by one time revolution. Resultantly within a burner wherein the fuel quantity is fluctuated corresponding to the output requirement while the blowing quantity is regulated corresponding to the fuel quantity, if the burning air is fed from the capacity type blower, optimum air quantity may be fed corresponding to the fuel quantity.

Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は燃焼器における強制給気方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a forced air supply method in a combustor.

（従来の技術） 一般に燃焼器を良好な状態で燃焼させるには、燃料と空
気との比率を適正に保つ必要がある。(Prior Art) Generally, in order to achieve good combustion in a combustor, it is necessary to maintain an appropriate ratio of fuel and air.

しかも燃料は各時点で器具に要求される出力に応じ制御
されるものであり、空気量は燃料供給率に応じて最適に
制御されることを要する。Moreover, the fuel is controlled according to the output required of the appliance at each point in time, and the amount of air needs to be optimally controlled according to the fuel supply rate.

しかしながら従来送風機は、シロッコファン、ターボフ
ァン等いわゆる回転翼型、遠心型と称すレｒ　イるもの
を用いているため、排気筒、風速等の外部条件の変化に
よって風量が著じるしく変動する無点を有していた。However, because conventional blowers use so-called rotary vane type or centrifugal types such as sirocco fans and turbo fans, the air volume fluctuates significantly due to changes in external conditions such as the exhaust stack and wind speed. Had no points.

（発明が解決しようとする問題点） 本発明は上記従来の難点に鑑がみなされたものであり、
低損等外部条件の如何にかかわらず風量の変化がほとん
どない燃焼器を提供せんとするものである。(Problems to be Solved by the Invention) The present invention has been made in consideration of the above-mentioned conventional difficulties.
It is an object of the present invention to provide a combustor that has low loss and has almost no change in air volume regardless of external conditions.

（実施例） 本発明は燃焼器の燃焼用空気を容積型送風機により供給
し、かつ燃料量の変化に応じて容積型送風機の回転数を
制御し空燃比を保つようにしたものである。(Embodiment) In the present invention, combustion air for a combustor is supplied by a positive displacement blower, and the rotational speed of the positive displacement blower is controlled according to changes in the amount of fuel to maintain the air-fuel ratio.

本発明において特に送風機を容積型とした理由は、容積
型送風機においては１回転で送風容量が定まるため、送
風量がほぼ一定になる点に着目したものである。In the present invention, the reason why the blower is particularly of a positive displacement type is that in a positive displacement blower, the air capacity is determined by one revolution, so the amount of air blown is almost constant.

従って燃料の量を要求出力により対応増減させ、送風量
を燃料量に応じて変化させる燃焼器において、燃焼用空
気を容積型送風機により供給すれば、燃料量に応じて常
に最適の空気量が得られるのである。Therefore, in a combustor that increases or decreases the amount of fuel depending on the required output and changes the amount of air blown depending on the amount of fuel, if the combustion air is supplied by a positive displacement blower, the optimal amount of air can always be obtained depending on the amount of fuel. It will be done.

（発明の効果） 本発明においては容積型送風機を燃焼器に用いたので、
排気筒、風速等の外部条件の変化にかかわらず風量の変
化をほとんど受けず、燃焼器を常に良好な状態で燃焼さ
せることができる。(Effect of the invention) In the present invention, since a positive displacement blower is used in the combustor,
Regardless of changes in external conditions such as the exhaust stack and wind speed, there is almost no change in air volume, and the combustor can always perform combustion in good conditions.
