COMMERCIAL BOILERS

A packaged Steam and Hot Water Boiler for Commercial Use

The Cyclotherm Steam and Hot Water Package Boiler is a complete unit in a single package ready for installation and efficient, economical operation for either high- or low-pressure steam or hot water applications. A minimum of 80% efficiency plus saving up to 1/3 the space formerly required are peaks of advanced design unsurpassed by any other make of package boiler.

All Cyclotherm units are designed and manufactured utilizing the simplified, proven and efficient two pass modified scotch marine boiler design – and incorporating the exclusive, patented method of Cyclonic Combustion. On 15 to 60 HP units, the burner shuts down when steam needs are satisfied. Precision modulation controls the larger units that operate from 20 to 100% of capacity with no loss in efficiency.

Cyclotherm boilers are manufactured to the highest standards of tolerance and A.S.M.E. quality control is made possible by creative engineering, and constant refinement of manufacturing procedures. Skilled, experienced technicians construct every unit to meet the most exacting requirements used in the United States boiler industry today. Each Cyclotherm measures up to every standard of true boiler value.

Clean, complete burning Cyclonic Combustion limits harmful stack emissions and particulate matter. This important safety feature is in direct relation to environmental concerns shared by Cyclotherm and the Environmental Protection Agencies. Through research and development, Cyclotherm has developed a low NOX burner kit that not only keeps your boiler compliant with local emission standards, but also saves fuel during operation through increased combustion efficiency. These burner kits can be supplied with new boilers ordered or can be retrofit onto existing Cyclotherms in the field.

Since the average life of a commercial package boiler is assumed to be in the vicinity of 45 or 50 years under normal operating conditions, maintenance must be considered the most important cost factor. Because only one return pass is needed to gain maximum thermal efficiency, Cyclotherm eliminates the useless bulk and weight of several banks of tubes and critical expendable refractory baffles; arrangements that are required in three and four pass package boilers. Also, because of our efficient 2 pass design and patented Cyclonic Combustion, the temperature distribution across the rear tube sheet is extremely uniform which eliminates high to low temperature gradient warpage of the rear tube sheet as seen on other manufacturers multiple pass boiler designs.

Field repair expenses are constantly on the increase. Cyclotherm boilers are designed for minimum maintenance. Experience proves costs are approximately ONE THIRD the average required for three and four pass boilers, especially retubing and refractory replacement, if necessary. This saves not only maintenance dollars, but more importantly, extended costly downtime.

Benefits of the Cyclotherm Steam / Hot Water Boiler

- Up to 1/3 Smaller. The simplified two pass modern design of Cyclotherm package Steam or Hot Water Boilers provide maximum capacity from minimum space. Plant growth can offer flexibility and overall maximum efficiency by adding units as required with minimal capital expenditure.
- Dual Fuel Systems. Cyclotherm Boilers are designed to operate efficiently on either oil or gas. A combination fuel system can be furnished to take advantage of fluctuations in fuel supply or price with only the flip of a switch, or by automatic control.
- Easy, Low-Cost Installations. Cyclotherm boilers arrive ready for operation. Only simple connections for fuel, water, electrical and stack are required to meet applicable codes. Many customers have installed units with maintenance personnel who can operate any Cyclotherm boiler.
- Assured Safety. All Cyclotherm boilers are built under the highest quality control standards. Complete and reliable fail-safe operation, designed for unattended operation. Our boilers can be made to comply with Factory Mutual, IRI, local ordinances, and other specifications as desired. Cyclotherm units are protected and fail safe in case of an interruption in fuel supply, lack of water, air or any electrical breakdown.
- Guarantee Operating Efficiency. The standard Cyclotherm models have been fire-tested and certified for performance, capacity and efficiency in accordance with those agencies establishing the highest industry standards. All units are pre-tested prior to shipment. Cyclotherm Package Steam and Hot Water Boilers are guaranteed to operate at a minimum of 80% thermal efficiency. Average units in the field today, operating on oil are at 83% plus efficiency.

CYCLOTHERM’S PATENTED CYCLONIC COMBUSTION

The Cyclonic Steam and Hot Water Boiler is a modified Scotch marine design operating on the exclusive, patented principle of Cyclonic Combustion. In only two passes, Cyclotherm achieves a minimum guaranteed 80% efficiency. Standard capacity ranges from 15 to 750 hp…from 15 to 200 psi. Higher design pressures are also available.

Cyclonic Combustion maintains perfect flame control for the diameter and length of the furnace. Combustion was photographed in the Cyclotherm boiler, an image of which is shown at the right, by merely swinging open the rear door. Ordinary boilers would require protective devices or shields for a similar demonstration showing the flame pattern.

How it Works

1.

At a tangent, air is injected into the cylindrical combustion chamber at a velocity of up to 200 miles per hour. The air mass assumes a cyclonic shape and motion in the firetube.

2.

Seconds later, the fuel…either oil or gas…is injected into the hollow center of the air mass. Coordinated ignition then provides immediate combustion with maximum safety.

3.

After ignition, the atomized fuel vaporizes, forming a swirling vortex of flame that spirals the entire length of the furnace. A Thin layer of air separates the flame from the furnace wall.

4.

Cyclonic Combustion transfers approximately 65-70% of the heat through the firetube alone, with an additional 15-20% produced in the return tubes. Result: a minimum 80% efficiency.
