When power, fuel-air ratio is also remained unchanged.This is advantage, especially when heating utensil must be at it in big adjusting range
When changing in terms of power, for example, because should have small performance number for heating for the house of thermal resistance well however
There should be high performance number for beam worker commercial water.
Feeding for fuel can pass through very short pipeline such as in T hours but can be heated by being directed over
The pipeline of utensil carries out.Importantly, the main throttling of fuel just carried out in the opening in the narrow area of Wen and
It is not to have been carried out before.
Although the fuel control valve being typically provided in fuel infeed channel also throttles, fuel passes through.But this valve
Main task be to provide with can it is (preparatory) determination pressure (usually identical or substantially the same as environmental pressure) combustion
Material, not for the throttling of fuel of fuel metering.Therefore, it should main throttling is interpreted as, it can be predetermined from having
The position that the fuel of pressure is provided is risen, and throttling not stronger than the throttling in opening carries out.
By the feature enumerated in the dependent claims, it is according to the advantageous remodeling of the heating utensil of independent claims
It is possible.In this way, feeding proportionate relationship when opening is ring-shaped gap and being further improved.The infeed of fuel makes Wen as a result,

Speed substantially along fuel-air mixing arrangement inner wall flow when, obtain another improvement.Pass through this on inner wall
Kind avoids such region, in this region, fuel is fed into and thus interferes with to the direction of opening again along flowing
The pressure proportional relationship of Wen.The pressure energy of fuel be almost completely converted into the high energy of flow of speed and fuel along
The diffusion wall of Wen prevents the formation of the recirculation zone on diffusion wall.Diffuser is interpreted as slowly opening, conically opens
Flow channel.Diffuser is a part of Wen.
In particularly simple, constructivity implementation, opening is constituted between matrix and casing.Then, if casing phase
It is removable for matrix, then it can change the size of opening by this method.
When casing and matrix are connected with each other by screw thread, the change of opening is particularly simply realized.
When being provided with pressure-regulating valve, stress level can be adjusted particularly simple.
