Title:
COMBUSTOR AND AMMONIA ENGINE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/234110
Kind Code:
A1
Abstract:
A combustor (40) has: a housing (41) having an open first end and a closed second end (41b); an introduction unit that introduces fuel and oxidizing gas into the housing (41) so that a tubular flow (F1) is generated within the housing (41); a spark plug (44) disposed at the second end (41b); and an ignition unit that generates a spark (P1) between a positive electrode (45) and a negative electrode (46) of the spark plug (44). The positive electrode (45) and the negative electrode (46) are arranged in a position such that a distance (L1) between the positive electrode (45) and the negative electrode (46) is shorter than a distance (L2) between the positive electrode (45) and an inner peripheral surface (41d) of the housing (41), so that a flame (P2) generated between the positive electrode (45) and the negative electrode (46) by the spark (P1) is formed only in a negative pressure region (A1) that is generated in a part of the housing (41).
