Determination of the flow rate in the inclined inlet holes of the quenching ring in the gasifier
Thread Content
As the title suggests, I’m a complete beginner. I would like to ask everyone: what factors determine the flow rate of water in the inclined holes of the quenching ring in a vaporization furnace? :(
It’s going to sink :('(:'(:'
When operating, I only pay attention to the flow rate; I’ve never really paid attention to the velocity.
The flow rate has a significant impact on the service life of the water ring; if we are to do the calculations, should we consider only the flow rate, which is determined by the cross-sectional area of the inlet hole?
How long can the quench ring last? During routine maintenance after more than 1 year of operation in a long cycle, the quench ring is usually replaced to enable further long-cycle operation. The cooling ring also suffers from severe scaling.
As I understand it, it is related to the water inflow rate and the diameter of the inclined hole
The main requirement is to ensure an appropriate distribution of the water film. We have previously adjusted the diameter of the inclined holes; since the amount of quenching water used is at almost the maximum level, the distribution of the quenching water is quite good. In my opinion, it is still necessary to consider the issue of the quench water cascade value; at the same time, it is important to maintain a water film, which serves as a way to protect the downcomer
The low lifespan of the quenching ring is not necessarily caused by flow velocity; you need to check the quality of the water. Flow velocity is determined by flow rate and cross-sectional area, and this can be calculated
The flow rate mainly depends on whether the water distribution in the quenching ring is uniform, with a uniform water film distribution
