Kwanza Sul Slaughterhouse – Angola
Project Description
Giconmes has installed two electric steam boilers at the slaughterhouse in Kwanza Sul, Angola. Each of these boilers, with a capacity of 180 kW, is designed to generate more than 250 kg of steam per hour, thus providing a continuous and powerful source of energy.
Original situation:
Challenges posed by the client:
Need to heat water to supply 350 liters/hour at 82ºC without using fossil fuels. They also needed a modular power source to be able to adapt electricity consumption according to production needs.
Giconmes suggested the installation of electric steam boilers with a capacity to produce 250kg/hour of steam. Steam is used as a heat transfer medium for heating water through a heat exchanger. The hot water produced is used for food preparation and cooking processes.
Proposed solution:
Customized steam solution developed by Giconmes.
Proposed solution:
Boilers connected to steam-water heat exchangers, an ingenious solution that maximizes system efficiency. The connection will allow the efficient production of 350 liters of hot water at 82ºC per hour. This optimized process not only ensures efficient throughput, but also improves the utility of the steam generated, thus benefiting the slaughterhouse operations.
The choice to use electric technology to power these boilers reflects a commitment to energy efficiency and sustainability. The strategy not only optimizes steam generation, but also contributes to the reduction of the slaughterhouse’s environmental footprint.
Technology used:
Two SKID platforms each consisting of:
- Boiler NGV60180 of 180kW manufactured with all components in AISI-316 and safety valve at 9.5 bar.
- Condensate tank – DRC00160 Condensate recovery tank of 160 liters with all components in contact with water made of stainless steel AISI A-304. Includes level regulator, solenoid valve and thermostat.
- Water softening system Equipment to reduce the total hardness of the water used to feed the boiler to admissible values that guarantee its durability. A mains pressure of not less than 2.5 bar and not more than 6 bar is required.
- Dechlorinating filter: A mains pressure of not less than 2.5 bar and not more than 6 bar is required.
- Flushing system: Flushing tank that discharges water at set intervals to facilitate cleaning and decalcification of the water.

FAQs
We understand that many questions may arise. Here are some of the most common ones.
There are no emissions beyond those produced during the electricity production process. Consequently, emissions can be neutral depending on the electricity mix. Electric steam boilers are the present and the future.
Absolutely. In fact, it is recommended to achieve maximum efficiency. There is no problem with remote control as long as it complies with current regulations.
A steam generator is a pressure vessel that, together with the piping network, is subject to regulatory control and complementary technical instructions, according to the regulations published in Royal Decree 809/2021, of September 21. Maintenance is divided into a part that can be easily fulfilled by the owner:
- Know and apply the manufacturer’s instructions regarding use, safety measures, and maintenance.
- Not to put the installation into service or prevent the operation of pressure equipment if the requirements of the Regulation are not met.
- Having at least the following documentation for the pressure equipment while they are installed: Declaration of conformity, manufacturer’s instructions (if applicable), and, if necessary, installation certificate, along with other supporting documentation (such as installation project, record of the last periodic inspection, certifications of equipment repairs or modifications, and any other documentation required by the relevant technical instruction complementary to this regulation). For detailed contents, refer to Annex IV of the regulation. Making this documentation available to the competent authority of the autonomous community and the companies responsible for maintenance, repair, or periodic inspections.
- Use the pressure equipment within its intended operating limits as specified by the manufacturer and take it out of service if it no longer meets the necessary safety requirements.
- Perform maintenance on the installations, pressure equipment, safety accessories, and control devices in accordance with the operating conditions and manufacturer’s instructions, and examine them at least once a year.
- Arranging for the necessary periodic inspections as required by Article 6 of the regulation.
- Having and maintaining an up-to-date record of pressure equipment categories I to IV, as defined in RD 709/2015, of July 24, or equipment similar to these categories according to Article 3.2 of the regulation, as well as their installations.
It is known that by applying heat to water, it transforms into steam at the boiling point and atmospheric pressure. From there, depending on the required saturation degree of steam for its proper application, we need to increase the pressure to obtain a higher temperature. To change the temperature and saturation degree of steam, we always need to modify the pressure.
It is a unit of pressure equivalent to 1 kg/cm2, 0.98 atmospheres, or 14.50 PSI.
