The invention discloses an
ammonia storage area liquid ammonia power
system for
ammonia-doped
combustion of a
coal-fired boiler, which comprises a
liquid ammonia storage tank area, a
liquid ammonia storage tank control room, a liquid
ammonia pump control valve group area, an
ammonia storage area safety
cofferdam, an ammonia leakage alarm
system, an external
electric control system, a cooling circulation system, a
nitrogen purging system, an automatic spraying system and an ammonia leakage
visual monitoring system, the invention relates to the technical field of ammonia-doped
combustion of
coal-fired boilers. According to the
ammonia storage area liquid ammonia power system for ammonia-doped
combustion of the
coal-fired boiler, the redundancy technology is adopted, the liquid ammonia outlet is formed in the two-thirds position below the liquid
ammonia storage tank and located below a liquid level
display device of the liquid ammonia
storage tank, it is guaranteed that the liquid ammonia outlet
pipe has liquid ammonia output with certain
potential energy, meanwhile, gas-liquid separation can be achieved, and the liquid ammonia output efficiency is improved. The liquid ammonia pump is guaranteed to suck pure liquid instead of a gas-liquid mixture, the
cavitation phenomenon of the liquid ammonia pump is restrained,
noise of the liquid ammonia pump and pipeline vibration are reduced, the performance of the liquid ammonia pump is improved, and the service life of the liquid ammonia pump is prolonged.
