Abstract

Niniejsze zgłoszenie dotyczy montowanego w pojeździe układu do wytwarzania wodoru z krakowania amoniaku w silniku amoniakowym oraz przeznaczonego do tego sposobu zarządzania termicznego. Przedstawiony na rysunku układ zawiera zbiornik magazynowy ciekłego amoniaku, zbiornik wstępnego ogrzewania ciekłego amoniaku do zgazowania, przewód rurowy wytwarzania wodoru, przewód rurowy magazynowania gazu krakingowego, rurę mieszania wstępnego kanału wlotowego amoniaku i wodoru, przewód rurowy do wytwarzania ciepła utleniacza amoniaku, przewód rurowy transportu powietrza i przewód rurowy transportu gazu resztkowego. Ciepło z przewodu rurowego do wytwarzania ciepła utleniacza amoniaku nie tylko dostarcza ciepło do krakowania amoniaku, ale także wstępnie ogrzewa amoniak wymagany do krakowania amoniaku; amoniak wymagany przez przewód rurowy do wytwarzania ciepła utleniacza amoniaku jest wstępnie ogrzewany, a ciepło jest wspólnie dostarczane do układu oczyszczania końcowego we współpracy z ciepłem gazu resztkowego silnika; proporcja molowa ilości dostarczanego amoniaku do ilości powietrza jest regulowana zgodnie z warunkami użytkowania silnika, tak aby zmienić uwalnianie ciepła z przewodu rurowego do wytwarzania ciepła utleniacza amoniaku, a reakcja jest przeprowadzana w najbardziej odpowiednim równaniu reakcji, dzięki czemu unika się generowania zanieczyszczeń gazu resztkowego; ponadto ciepło z przewodu rurowego do wytwarzania ciepła utleniacza amoniaku jako rdzenia jest rozprowadzane i kierowane.The present application relates to a vehicle-mounted system for generating hydrogen from the cracking of ammonia in an ammonia engine and a thermal management method therefor. The system shown in the drawing comprises a liquid ammonia storage tank, a liquid ammonia gasification preheating tank, a hydrogen generation piping, a cracking gas storage piping, an ammonia and hydrogen inlet duct pre-mixing piping, an ammonia oxidizer heat generation piping, an air transport piping, and a tail gas transport piping. Heat from the ammonia oxidizer heat generation piping not only supplies heat for ammonia cracking but also preheats the ammonia required for ammonia cracking; the ammonia required by the ammonia oxidizer heat generation piping is preheated, and the heat is jointly supplied to the aftertreatment system in cooperation with the engine tail gas heat; The molar ratio of the ammonia supply amount to the air amount is adjusted according to the engine operating conditions to change the heat release from the ammonia oxidizer heat-generating pipe, and the reaction is carried out in the most appropriate reaction equation, thereby avoiding the generation of tail gas impurities; in addition, the heat from the ammonia oxidizer heat-generating pipe as the core is distributed and directed.
