Waste heat units
Cyclotherm has been designing and manufacturing Heat Exchangers of all types for over 50 years.
Cyclotherm has been designing and manufacturing Heat Exchangers of all types for over 50 years.
Starting in 1965, special attention was directed toward Waste Heat Recovery Units, including Acid Gas Burning and Sulphur Recovery types. Since then we have supplied many such units, each individually tailored to the job requirements, whether it be one, two, three, four or five gas passes. Some were for steam production; some water heating in the normal 180°-200° temperature range and some for heating various glycol-water mixtures up to 350°F. Pressures ranged from 15# steam – 30# water to 300# steam.
The savings made possible by utilizing heat otherwise ignored or wasted, are shown on the curves on this brochure.

Sulfuric Acid Coolers
Shop views of typical medium size stainless steel H2SO4 coolers for contact plant absorber tower and drying tower service. Note single pass tube side construction to handle acid under optimum velocity and metal temperature conditions. This avoids the necessity of sophisticated electronic passivation and monitoring apparatus.
Water flows through shell in a divided flow configuration for maintaining tube side metal temperatures using abnormally warm water from a closed water to air cooling system. This type of installation is particularly suited for use in scarce water areas.
Note the oversized inlet distribution belts combined with shell expansion joints.

Simplicity of design, rugged construction
Strong Acid Coolers, as shown here, reflect the simplicity of design and ruggedness of construction that Cyclotherm builds into their heat exchangers.
Acid Passes through the tubes by means of simple cone type channel headers for inlet and outlet connections. Heavy wall (14ga) 316L tubes are TIG welded to the tube sheets for strength, positive seal and fair entry. Seal rolling to eliminate backside crevice is performed after welding. Design criteria for acid flow calls for 3 ft/sec. max velocity and 80°C max metal temperature which allows inlet acid temperature of up to 230°F. The shell side containing cooling water, is segmentally baffled and designed to limit water velocity to approximately 4 ft/sec. Cooling water should be cleaned and treated for scale prevention containing minimum chlorides or other halides which are deleterious to stainless steel. Inlets are installed on distribution belts which act as expansion joints and provision is made for cooling the tube sheets at inlet and exit. This cooler design can be utilized either vertically or horizontally.
Cyclotherm has a wealth of experience in the design and fabrication of gas exchangers for acid plants in any required material. The unit pictured below for SO2 exchanger service, is a typical example.
Digester Heater
Cyclotherm has a package unit for sewage sludge heating. The unit is a combination heat exchanger with an integral source of heat together with provisions for utilizing heat from natural gas engines. Complete automatic operation is provided. The Cyclotherm method of combustion is primarily responsible for the high efficiencies realized by this heater. The Cyclotherm burner, an integral part of the unit, provides automatic conversion from sewage gas to an auxiliary fuel. In addition to the high efficiency and flexibility, this unit is characterized by compactness, low cost of maintenance, and ease of control.
