The ZDKI steam boiler is an immersion type electrode boiler. It has an outer vessel and an inner tank. Water circulates between the outer and inner tank. Power is regulated by the water level in the inner tank, ie, the amount of water in contact with the electrodes. This gives the ZETA boiler very fast startup time and modulation rage between 3-100%. ZETA Steam Boilers accepts power between 5-70MW. It can produce high steam pressure up to 950 psig. Its efficiency is nearly 100% without the only energy loss through insulation and blowdown. Due to large steam space of the immersion boiler and very calm steaming surface, it can generate very clean steam with very little carryover. That is one the reason why ZETA steam boilers are the preferred auxillary boilers in the nuclear power plant, where they require 99.9+% steam quality.
High steam pressure up to 950 psig
Very high steam quality (>99.9%)
Very fast startup from hot standby (<5 mins)
Inherently safe - low water auto shutoff
