Economizer, Recuperator, Superheater

ENEVA economizers, superheaters, and recuperator systems are high-efficiency heat recovery equipment designed to reclaim waste heat from boiler, furnace, or process flue gases back into the system without additional fuel consumption. These systems increase energy efficiency, reduce fuel consumption and emissions, and directly contribute to lower operating costs.

• Recovery of flue gas waste heat
• Preheating of feedwater, process fluids, or combustion air
• Custom engineering design for boilers and processes
• Fuel savings and reduced carbon footprint

WHAT DO THESE SYSTEMS DO?

Energy released to the atmosphere via flue gas represents a significant potential that is often wasted in many facilities. ENEVA heat recovery equipment is designed to convert this potential into useful heat.

General principle: Every 15–20 °C drop in flue gas temperature provides approximately 1% fuel savings.

SYSTEM TYPES

Economizers

Utilize flue gas energy to preheat boiler feedwater or process water.

• Increases boiler efficiency
• Reduces thermal shocks
• Extends equipment lifetime

Superheaters

Used to raise the temperature of steam or process fluids. Commonly applied in energy generation and process applications.

• For processes requiring dry steam
• Improves performance in turbine applications

Recuperators (Air Preheaters)

Recuperators preheat combustion air using flue gas energy, increasing thermal efficiency. They serve as an alternative heat recovery solution in facilities where feedwater or process fluids cannot be preheated.

• Preheating of combustion air
• Improves burner and boiler performance
• High savings in thermal oil and high-temperature boilers
