HRC Steam and Hot water Systems

Steam or Hot water on demand and maximum output in less than 2 minutes from a cold start as opposed to conventional boilers, which may take up to 1 to 2 hours.

This will conserve energy and reduce costs  & emissions.

Rapid Start

Steam on demand and maximum output in less than two minutes from a cold start as opposed to conventional boilers, which may take up to 1 to 2 hours.  Increase productivity, Reduce costs & emissions.

Pre Purge

Pre-purge energy losses through stack are minimum. Pre-purge ensure that combustible gases from previous firings are removed prior to ignition.

Specs’

HRC Steam Systems have a small footprint and weigh less than conventional boilers of the same capacity.

Dimensions

Dimensions of all modules (including the pump and control unit) are;  width 400 mm x Height 2000 mm x Length x 1200mm.

Important Features

  • Modular and space requirement
    The HRC modular units can connect up to 5 combustion units with a single pump module. Each module is capable of producing approximately 400kg of steam per hour (185 degrees Celsius at 10 Bar). Attached to the combustion units will be a pump and control module which will include a steam separator and condensate trap if required. The small dimensions of the HRC steam generators allows for smaller units to be located around the production facility to provide “instant” localised steam “on demand” production (rather than a large central steam boiler system).
  • Applications
    Conventional boiler systems are generally not good or capable to handle load swing variations. HRC is suited but not limited to these applications
  • Retrofit applications
    Where additional steam capacity is needed and floor space or physical access is limited. The HRC steam generators have generally a 40 to 60% smaller footprint.
  • Cyclical loads
    Facilities that experience drastically reduced steam load, the HRC steam generator alone can often carry the reduced load. This allows the conventional boiler to be removed from service, saving fuel and maintenance cost.
  • Short duration swing loads
    In operations that experience load swings of relative short durations. Such as batch loading, sterilisation, pasteurisation cycles or hotels, hospitals and multi dwelling apartment buildings that uses a portion of the steam for hot water and have peak periods of shower use or laundry operations, the conventional boiler can be base-loaded for normal steam demand and the swing load absorbed by the steam generator. The steam generator can be left cold and switched on when needed with less than 2 minutes start-up time vs. boiler heat-up time of hours. Fuel savings alone can often justify the cost.
  • Critical standby demand
    If a steam plant goes down it can be life threatening in hospitals and healthcare facilities or critical production processes, in these cases they must have backup steam capability. A HRC steam generator may offer a cost effective solution.
  • Low emission
    HRC technology is a giant leap forwards in reducing polluting greenhouse gas emissions. Near zero NOx emissions and a 20% reduction in CO2 emissions due to the enhanced heat transfer and short start-up.
  • Energy and Cost Saving
    The potential cost and fuel saving with the HRC is 30% to 50%. When we consider the cold start-up time, the greater heat transfer coefficient, small foot print and smaller plant room, no blow-down and low emissions and the steam on demand are among the multiple number of advantages that this system has to offer and savings can easily exceed the above figures.

Touch Points

Fuel

HFPD steam generator operates on LPG or Natural Gas.

Materials

The modules will be entirely constructed out of stainless steel

Steam Quality

At 185 degrees Celsius at 10 Bar pressure the HRC steam is dry and of high quality. Dryness fraction > 0.99, hence no product contamination. Pressure and temperature are fully adjustable to suit customer requirements.

Noise and Safety

The HRC units are less noisy than existing steam boiler technology and are safer to operate as they do not store large volume of water or steam under pressure.

Boiler attendant

The once through HRC steam generator does not require a full or part time boiler attendant. Designed for un-attendant operation.

Boiler Blowdown

No boiler blowdown and few chemical are required for the feedwater, except where poor water conditions exist.
