The high delta-T coil is very similar to the low delta-T coil, but it provide significant energy savings due to a 75% reduction in pumping energy, lower pressure drop on the air side, and low boiler
EWT in a coil that has less rows.
It also indicates the low boiler
efficiency under low firing rate.
We are not utilizing traditional way of using waste heat recovery boiler to generate hot water or steam to feed Absorption Chiller as this system is not considered as energy efficient system because of low boiler
efficiency and low COP of hot water chiller.
The boiler's automatic feed system and intelligent control panel require low boiler
operator involvement to monitor all functions of the system, Lyman explained.
Most biomass power plants operating today are characterized by low boiler
and thermal-plant efficiencies; both the fuel's characteristics and the small size of most facilities contribute to these efficiencies.
