Principal of Operation

TOMCO2's IMP-JET Recarbonators operate on the principal of producing carbon dioxide (CO2) by burning a gaseous fuel beneath the surface of the water being treated. By producing only as much CO2 as required by the particular water flow and by the treatment conditions existing at the moment, the TOMCO2 unit excels in simplicity of both installation and operation. The air-gas mixture in the TOMCO2 submerged burner is of almost theoretical proportions. Combustion yields a gas of maximum CO2 content. The enormous energy change that occurs when this type of burning takes place causes the gases to be subdivided into countless tiny bubbles offering maximum surface area for high absorption efficiency.

Capacity

Available sizes range from 400 pounds (181.4 kg) to 10,000 pounds (4,536 kg) of CO2 per day per unit. When total requirements are over 10,000 pounds (4,536 kg) per day, it has been found more desirable to have multiple units to give greater flexibility . . . although a single burner with larger capacity can be furnished. Each TOMCO2 recarbonator can be operated from 50 to 100 percent of rated capacity. Past records actually show that these units are operating in the range of 30 to 100 percent of capacity.

Models Available

TOMCO2's IMP-JET Recarbonators are available in two different models:
  • Manual - In which the ratio of air and gas is automatically controlled and the CO2 output is manually varied.
  • Automatic - in which the air-gas ratio is maintained automatically and the output of CO2 is regulated by the pH of the recarbonated water.

Ignition

All submerged combustion burners are electrically ignited. The flow of combustion air is first introduced to the burner. The igniter is then energized and allowed to heat for approximately 30 seconds. The proper ratio of gas is then introduced and ignition takes place. The igniter is de-energized and burning continues.

Basic Components

The essential parts of a TOMCO2 Recarbonator can be divided into four sections:
  • Submerged burner assembly with a stainless steel combustion chamber
  • Compressor Unit in which the combustion air, (and gas, if required), is compressed to overcome the hydrostatic head due to submergence of the burner.
  • Connecting piping wherein the air and fuel are metered, blended and delivered to the burner in the proper proportions to maintain combustion.
  • Control Panel on which all of the controls are centralized.

Submerged Combustion Burner
Recarbonation Chamber

The TOMCO2 Recarbonation Unit can be adapted to fit an existing or new plant. Because the IMP-JET burner is equipped with its own diffuser, elaborate grid diffusion systems are not required. Installation is simple and economical. Approximately 10 feet (3.05 m) of submergence is desirable for maximum absorption efficiency. The IMP-JET Submerged Burner, once placed in the recarbonating chamber, is seldom removed.

Fuels

TOMCO2 Recarbonators are applicable wherever gaseous fuels of reasonably uniform quality are available. Units are in operation burning natural gas, butane, propane and digester gas.


Safety Features

Each Recarbonator is equipped with a flame scanning system that automatically closes a magnetic valve in the gas line and sounds an alarm in the event of flame failure.
