Eneva products

Waste heat boilers are the equipment used in the production of process fluids such as steam, hot water or hot water by recovering this heat in processes where there is high temperature waste heat. For example, cogeneration plants, cement plants, glass factories or steel production process chimneys are potential sources for waste heat boiler application. Design and production with CE/ASME mark can be made according to EN12952 & EN12953 & ASME standards with smoke tube, water tube or combined. Depending on the operating time of the system, the payback period for installing such boilers may be limited to several years, so they are quite attractive systems to invest in. Our team has deep experience in the design, manufacture and turnkey installation of such systems.

In cases where hot water cannot be produced with waste flue gas heat, the most rational application is in the form of preheating the burner combustion air and using the waste heat in the flue gas. Especially since there is usually no water to be preheated in hot oil boilers and the oil temperature is too high, the most correct method is to heat the combustion air needed by burner. Recuperators are usually of tubular type and should be designed with the counter current and heat transfer optimization in the system in mind carefully. Especially in case of space problems in existing systems, special designs can be made and customer demands can be met with horizontal, vertical or combined designs. ENEVA has many successful reference applications on recuperator products.

Hot oil boilers are systems that can produce heat under low pressure in high temperature applications. The oil used in hot oil boilers does not deteriorate in a short time it should be designed carefully in terms of, otherwise, the film temperatures in the boiler, i.e. the oil degradation rates, may rise and new oil may be required in a short time. It should be remembered that every 10 ° C rise in oil temperature doubles the rate of deterioration, that is, it significantly reduces the service life of heat transfer oil. One of the areas where our company is most engaged in the sector is the design and application of equipment & installations complete with hot oil boilers. These systems are designed by our company in accordance with the DIN4754 norm, are manufactured with high quality and can be delivered in working condition.

Our company can supply steam boilers and hot water boilers to its customers with years of design experience. Boiler systems of this type can be of the water or smoke-tube type and can be designed with additional economizers at a total efficiency of up to or above 100%. Depending on the boiler type, system designs can be made in accordance with EN12953 or EN12952 norms and are marked CE according to directive 2014/68 EU.
