The steam boiler system comprises a steam boiler comprising a burner and a chimney for exhausting flue gases, a feedwater line for leading feedwater to said steam boiler for producing steam, a steam line leading from said steam boiler to at least one application heat exchanger for feeding steam to said application heat exchanger, said application heat exchanger for heating an application fluid, and a condensate line leading away from said application heat exchanger for recuperating condensate from said application heat exchanger. An economizer heat exchanger is provided in said chimney, wherein at least one of said condensate return line and said feedwater line circulates through said economizer heat exchanger for allowing at least one of said condensate and said feedwater to be in heat exchange relationship with the flue gases for simultaneously cooling the flue gases while heating at least one of the condensate and the feedwater.
F22D 1/02 - Feed-water heaters, e.g. preheaters with water tubes arranged in the boiler furnace, fire tubes or flue ways
F22D 1/34 - Feed-water heaters, e.g. preheaters arranged to be heated by steam, e.g. bled from turbines and returning condensate to boiler with main feed supply
The heat exchange system includes a flooded heat exchanger unit where a first fluid is heated by a second fluid. The flooded heat exchanger has a second fluid circuit control valve at its downstream end. A steam detection device is connected to the second fluid circuit downstream of the heat exchanger. A fail-closed/normally closed valve is located on the second fluid circuit downstream of the heat exchanger. A fail-closed/normally closed valve actuator controls the fail-closed/normally closed valve to maintain it in its opened condition against the action of the normally closed mechanism of the fail-closed normally closed valve. If steam is detected in the second fluid circuit downstream of the heat exchanger and upstream of the second fluid circuit control valve, the fail-closed/normally closed valve actuator will switch to its closed condition to shut off fluid flow to the second fluid circuit control valve.

The heat exchange system is for heating water from a water source and comprises first and second flooded heat exchangers that have steam sides that are each independently fed with steam, but water sides that are serially fed with water through the first heat exchanger then through the second heat exchanger. The system also comprises first and second control valves located at or downstream of subcooled condensate outlets of the first and second heat exchangers, first and second water temperature sensors at or downstream of the heated water outlets of the first and second heat exchangers, and a control device for receiving temperature data from the first and second water temperature sensors and for controlling the first and second control valves. The proportions of the first and second steam sides that are flooded are respectively selectively adjusted by controlling the debit of condensate allowed through the first and second subcooled condensate outlets with the first and second control valves, for allowing heat exchange to the water to be adjusted as a result of the water temperature measured by the first and second water temperature sensors. The first and second control valves are set in one of a first state in which they are both at least partly opened to allow effective heat exchange from the steam to the water in both first and second heat exchangers, and a second state in which one of them is closed while the other is at least partly opened to have an effective heat exchange from the steam to the water in only one of the first or second heat exchangers while the first and second steam sides remain both supplied with steam.

The system and method of controlling a level of flooding to remain substantially constant within a flooded heat exchanger wherein steam flows into a steam side and condenses to form condensate that partly floods the steam side and that flows out of the steam side, and wherein cold water flows into a water side in heat exchange relationship with the steam side to heat the cold water and form heated water that flows out of the water side, comprises collecting the water condensate flowing out of the heat exchanger condensate outlet into a level controller through a controller condensate inlet; connecting the level controller to a steam source having a pressure equivalent to that of the heat exchanger steam side; and controlling the level of condensate in the level controller to remain substantially constant with a controller valve that allows condensate to be exhausted out through a controller condensate outlet if the level of the condensate in the level controller rises beyond a valve activation threshold wherein the level of condensate in the heat exchanger steam side will also be controlled to remain substantially constant consequently allowing a level of flooding in the flooded heat exchanger to remain substantially constant.

Method of controlling the saturation level of a generated gaseous state fluid
The method of controlling the saturation level of a gaseous state fluid generated at an outlet of a gaseous state fluid generation system comprises measuring a reference parameter of the fluid other than the saturation level itself, with the reference parameter being representative of the saturation level, and selectively superheating the fluid as a response to the measured reference parameter until the reference parameter falls within an acceptable range of reference parameter values.
