Coatings for enhancing performance of materials surfaces, methods of producing the coating and coated substrates, and coated condensers are disclosed herein. More particularly, exemplary embodiments provide chemical coating materials useful for coating condenser components.

A heat recovery steam generator (HRSG) (10) including: an economizer (12) configured to heat a working fluid by extracting heat from a flow of flue gas (20). The HRSG includes a diluting fluid injector arrangement (60) configured to inject a diluting fluid (50) effective to dilute a concentration of a gaseous corrosive when compared to an undiluted concentration of the gaseous corrosive in the flow of flue gas. The HRSG also includes a preheater (18) configured to preheat the diluting fluid prior to injection.

Presented herein are articles and methods featuring substrates with thin, uniform polymeric films grafted (e.g., covalently bonded) thereupon. The resulting coating provides significant reductions in thermal resistance, drop shedding size, and degradation rate during dropwise condensation of steam compared to existing coatings. Surfaces that promote dropwise shedding of low-surface tension condensates, such as liquid hydrocarbons, are also demonstrated herein.

Improved heat exchangers and methods of manufacturing the heat exchangers are provided. The methods include modification of surface(s) of the heat exchanger in an integrated manner during manufacturing, to impart desired properties such as decreased corrosion, pressure drop, and water retention, and increased anti-frosting performance.

Control systems are provided that provide thermodynamically decoupled control of temperature and relative humidity and/or reduce or prevent frost formation or remove previously-formed frost. The control systems herein may be included as a component of a heating, ventilation, air conditioning, and refrigeration system that includes a heat exchanger.

A method of designing a gas cooler includes acquiring information on a condition of a gas flowing through a flow path in a shell main body and a condition of a cooling medium flowing through at least one pipe; setting a provisional arrangement condition of the at least one pipe when viewed from a second direction intersecting a first direction in which the gas flows in the flow path; and acquiring a relationship between an adhesion rate of condensed water of moisture contained in the gas to an outside surface of the at least one pipe and a decrease rate of an efficiency of heat exchange between the gas and the cooling medium on a basis of the acquired information on the condition of the gas, the acquired information on the condition of the cooling medium, and the set provisional arrangement condition.
