Vapor Power International products

The Circulatic® Watertube Steam Generator is a forced recirculation watertube boiler that uses a drum as a steam separator and a reservoir of water to supply the coils. A recirculating pump draws the water from the drum and forces it through a set of parallel connected coils at the rate of 3 to 4 times the maximum steaming rate. The hot gases envelop the entire tube surface to achieve very high heat transfer rates. The water is then pushed through a steam lance and a series of baffles in the drum where some of the water is flashed into steam and separated. The dry steam is released and the water is recirculated through the coils. The fuel and combustion air is controlled by a linkageless fuel air ratio control that responds to steam pressure. The feedwater is controlled by a water level control system and modulating feedwater valve.

Vapor Power electric hot water boilers are designed to provide fast, efficient, and economical hot water for heating and process through the use of electric resistance elements. The boiler controls automatically energize/de-energize steps of elements to maintain the desired water temperature. All boilers utilize ASME pressure vessels and all electrical components are UL listed and are wired in accordance with the current National Electrical Code requirements. Each boiler is insulated with 3-1/2″ fiberglass secured to the vessel, and is housed in a heavy-gauge sheet metal cabinet mounted on a full size structural steel base. All Vapor Power resistance style boilers utilize 70 to 75 wpsi Incoloy-sheathed elements configured in conservatively sized circuits to allow for overvoltage conditions as great as 10% without adversely affecting the integrity of circuit components.

Vapor Power’s Electrode boiler creates operating advantages from its unique design which results in a high efficiency, high quality steam boiler. Using electricity as a clean, efficient and easily controlled fuel, all the energy input to the boiler is converted to steam with 99% efficiency. Vapor Power’s electrode generator output is controllable from 0-100%, with neither the limited turndown ratios nor the increasing inefficiency at low output conditions characteristic of fossil-fired boilers. There are no stacks to purchase and there are zero pollutant emissions.

The Vapor Power Superheater is a coil tube design, similar to our steam generators. Saturated steam enters at the inlet of the superheater, passes through a set of coils, and hot combustion gases envelop the entire tube surface to achieve very high heat transfer rates. Superheated steam leaves the superheater at the steam outlet manifold. The fuel and combustion air is controlled by a linkageless fuel air ratio control that responds to steam temperature.

Vapor Power’s pressurized spray deaerators will reduce the oxygen level to the .005 cc/liter or less and carbon dioxide to zero. A deaerator consists of a pressure vessel in which water and steam are mixed with controlled velocities and the rapid removal of gases results when the liquid is sprayed in thin films and intensely scrubbed by the incoming steam. This raises the water temperature, thereby liberating the dissolved, non-condensable gases; and the water is then considered free from corrosive gases.
