Title:
COMBUSTION EFFICIENCY IMPROVEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/090027
Kind Code:
A1
Abstract:
Provided is a combustion efficiency improvement device with which it is possible to improve combustion efficiency of a combustion device that burns liquid fuel. The combustion efficiency improvement device (1) according to the present invention is for improving combustion efficiency when liquid fuel (F) is burned in an external combustion device (200), and comprises: branch channels (20) which are incorporated such that the upstream sides thereof are separated from and the downstream sides thereof are merged with a main channel (10) for delivering the fuel (F) from an external fuel supply source (100) to the combustion device (200); nozzles (30) that are for generating bubbles (B) and are incorporated in the branching channels (20); and a pressure pump (22) for applying a prescribed pressure on the fuel (F) to be delivered toward the nozzles (30). The nozzles (30) each include a cavitation generation unit (31) which does not have a port for taking in gas from outside but is configured to cause a cavitation phenomenon while the fuel (F) under the prescribed pressure is being delivered, to thereby generate bubbles (B) in the fuel (F).
