The relationship between the air pressure of the combustion head and the boiler back pressure
Thread Content
Hello everyone. For oil and gas boilers, is the wind pressure at the combustion head outlet equal to the furnace back pressure of the boiler? I think that the pressure at the burner head outlet is greater than the furnace back pressure of the boiler. After the air from the burner head outlet enters the furnace, because the volume of the furnace is larger than the combustion chamber volume, the air pressure at the burner head outlet quickly drops to the same as the boiler back pressure. Is this view of mine correct? Please give me your advice. Thanks.

The static pressure head needs to increase. If it is the same as what you said, the smoke in the furnace hall will not be discharged.

For fire tube boilers, what is the relationship between the combustion head outlet pressure and the furnace back pressure? If the furnace back pressure is known, how to determine the combustion head outlet pressure?
This is Bernoulli's equation for fluids. What I mean is to verify whether the formula of the ideal gas equation of state (PV=nRT) is satisfied. When the temperature is constant, the volume increases and the pressure decreases. Can it be used to explain the relationship between the combustion head outlet pressure and the furnace back pressure?
