Abstract

The invention discloses a molten salt energy storage-based ammonia boiler for real-time cracking of ammonia fuel through magnetic ring enhanced rotating arc plasma, and relates to the technical field of new energy boilers. The molten salt energy storage-based ammonia boiler comprises an ammonia decomposition box, and the ammonia decomposition box comprises a plasma ammonia cracker, a temperature sensor, a gas pressure sensor and a hydrogen component sensor. Before mixed combustion with an air source, an ammonia fuel source firstly passes through the ammonia decomposition box, the ammonia fuel source is cracked in real time through a magnetic ring enhanced rotating arc plasma ammonia cracker, and ammonia / hydrogen mixed gas is prepared; and a plasma igniter and a plasma combustion-supporting device are arranged in a combustion chamber of the ammonia boiler. According to the molten salt energy storage-based ammonia boiler,the discharge power of the magnetic ring enhanced rotating arc plasma ammonia cracker is adjusted, so that the ratio of ammonia gas to hydrogen can be accurately adjusted, ammonia / hydrogen mixed fuel can be stably combusted in the boiler combustion chamber, an on-line ammonia boiler tail gas treatment system performs purification treatment on the tail gas by utilizing the existing ammonia fuel of a combustion system, and therefore, the emission standard is reached.

Description

technical field

[0001] The invention belongs to the technical field of new energy boilers, and in particular relates to an ammonia boiler based on molten salt energy storage plasma for real-time cracking of ammonia fuel, specifically an online real-time cracking of ammonia fuel, ignition and combustion support based on magnetic ring enhanced rotating arc plasma ammonia boiler. Background technique

[0002] Most of the current civil and industrial boilers use fossil fuels for combustion, but the CO produced during the combustion of fossil fuels 2 Causes a significant greenhouse effect, whether it is coal or natural gas, the carbon dioxide emissions of boilers contribute a considerable part of the greenhouse effect. To reduce the greenhouse effect, it is one of the necessary ways to replace or partially replace existing fossil fuels with new fuels. As a clean energy, hydrogen energy has a stable combustion process and high calorific value released by combustion. Storage and ...
