Can the flow restriction hole of the aqueous urea one-point heater be eliminated?
Thread Content
In the design, the aqueous urea one-point heater is equipped with limited flow holes, and the hole diameter is generally 5mm. However, in recent years, many manufacturers have expanded the diameter of the restriction hole to about 8mm, and some have even eliminated the restriction hole. Please discuss the setting of this restriction hole.: Can this restriction hole be eliminated? If it hadn't been cancelled, how big would your aperture be?
It is not advisable to cancel it. This restriction hole can play the role of rising film.
If it is a rising film heater, do not cancel the restriction hole. If the output is increased, the hole can be appropriately expanded. Otherwise it will affect the decomposition effect. This post was last edited by lxq700918 on 2009-3-3 22:33 ]
If it is a rising film heater, do not cancel the flow restriction hole.； Otherwise, the liquid film in the tube will be too thick and the heating effect will be poor. This post was last edited by lxq700918 on 2009-3-4 19:50 ]
