Waste heat recovery boilers

Steam waste-heat boiler is an industrial heat exchanger without a combustion chamber, designed to generate process steam through the use of waste heat.


The most effective devices for heat recovery is considered to be OPT heat exchangers. Such waste heat boilers are manufactured using heat-resistant steels, which significantly increase operational life compared to other types of waste heat boilers.

OPT heat exchangers are produced on request, the equipment is pre-calculated resulting maximum energy efficiency and optimal dimensions of the unit. The heat exchangers have a modular design, the module is assembled from steel plates, which form alternating channels for the passage of a heated and heated medium. Water is used to generate steam, the process of steam formation occurs due to exposure to high temperatures from the exhaust gases (for example, from a furnace in metallurgy).


Steam waste-heat boilers are used in various industries Collection and recycling of heat energy from exhaust gases allows saving fuel and direct the resulting steam to improve the efficiency of various technological processes.


The characteristics of the heat exchangers of OPT may vary depending on the requirements for this equipment. The main factors affecting the characteristics are the temperature of the medium, the area of the heat exchange surface and the flow rate.

In OPT steam waste-heat boilers, ribbed panels are used as heat transfer elements; they separate channels for passage of medium. The area of the panels can be controlled by the number of the panels in the module namely, as the number increases, the channel cross-section decreases, the resistance increases and the flow rate decreases, as a result, the unit performance increases. Changes in the characteristics can be carried out on the equipment already installed, the modular panel design allows quickly and easily changing the characteristics depending on changes in operating conditions.
