New insights into Claus waste heat boilers

To provide operability, this region of the WHB is protected by ceramic ferrules (see Figure 2) inserted a short distance into the tubes and which usually also completely cover the face of the tubesheet (see Figure 3). On the utility side, high or medium pressure steam is usually generated (heat recovery) by cooling the hot gas on the process side.

How do heat exchangers work? - Explain that Stuff

Photo: How a simple heat exchanger works. A hot fluid (shown in red) flows through a tube coiled inside a larger shell through which another, colder fluid (shown in blue) is running in the opposite direction. Heat is exchanged by the fluids: the hot fluid cools down and the cold fluid warms up, without them actually coming into contact and mixing.

Currently, we are seeking to develop PTCs with direct steam generation (DSG). This process consists of circulating water under pressure in the receiver tube to generate steam directly into the solar loop. This makes it possible to reduce the investment and maintenance costs of the PTCs (the oil-water exchangers are removed) and to avoid the
