Sugimat makes progresses in its international expansion by developing an HTF boiler for Agua Prieta CSP plant in the state of Sonora, Mexico. It is one of the most important power plants in Latin America. Sugimat’s installation, is part of the combined cycle plant Agua Prieta II, a combined cycle with increased performance and operating in conjunction with a solar field. The plant is a pioneering project in the country promoted by Mexico’s state-owned Federal Electricity Commission (CFE).

The installation, which uses DowTherm A heat transfer fluids and is capable of working up to 390 ºC, is integrated into the solar field production block and has been designed, manufactured and commissioned on a turnkey basis by Sugimat. It is a 6 MW HTF boiler that increases the performance of the combined cycle by 10 points and uses a natural gas burner with low NOx emissions. The CSP plant has a solar field of parabolic trough collectors of 14 MW and a natural gas combined cycle capable of producing up to 464,4 MW. Both are interconnected and form the first hybrid concentration solar power plant in Mexico, which provides an installed generation capacity of 394 MW to the country’s National Electric System.

Thanks to the use of natural gas as fuel, this hi-tech Integrated Solar Combined Cycle – ISCC plant will avoid more than 208,000 tons of carbon dioxide per year will cease to be released into the atmosphere, reducing the environmental impact.

The location of the plant in the state of Sonora has been a strategic decision. It is integrated in the “sun belt” and covers the area with the best solar radiation in the country, which makes it ideal for the operation of thermo-solar power plants.

The project, made by Abengoa, is financed by the World Bank, which through the United Nations Development Program, Global Environmental Facility, has allocated 200 million dollars to promote  thermo-solar technology in four countries, one of which is Mexico.

Last February, the Electric Metrology Laboratory (LME) of CIRCE, located in Zaragoza, obtained accreditation by ENAC (National Accreditation Entity) for carrying out the test to heating boilers for solid fuels, becoming the first laboratory accredited in our country under the UNE-EN 303-5:2013 standard. This accreditation will reduce the cost and complexity of the test benefiting from a nationally accredited centre.

Until now, there was no accredited laboratory in Spain so it was necessary to send the heating boilers to a foreign certified laboratory in order to perform the test. CIRCE carries out on site tests, displacing their own equipment to the customer facilities. This implies a reduction in transport costs, but on top of that a higher knowledge of the boiler and the test by the boiler manufacturer.

The scope of accreditation covers tests of heating boilers for solid fuels, manually and automatically stoked and a nominal heat output up to 500 kW and can determine the performance features, gas and particles emissions at rated and minimum power as well as safety requirements to be met by such boilers.

With this service, CIRCE will foster competitiveness of boiler manufacturers, favouring the market uptake of more efficient and sustainable boilers.

It is highly significant how Spain’s energy model for generating and distributing heating and DHW to residential blocks over past decades, that represent the majority in Spain, has tended towards an individualised system of “one boiler for every home”. Its application has prevailed thanks to the convenience of the piped distribution of gaseous fossil fuels (despite its risks) and by a legislation that has been lax in controlling the squandering of energy and also, make no mistake, due to individualistic consumer behaviour as part of this necessary collective process. The clear winners of this model are neither energy efficiency nor the consumers.

The economic crisis that has exponentially increased the number of homes in “energy poverty”, the concern for be pollution in the cities and the commitment to the climate (that translates into less energy cost per capita to contaminate less and to reduce CO2 emissions), are elements that are making every group of citizens think again to modify the current energy model insofar as this is possible.

One possible way to resolve these issues is to promote district heating and cooling networks. This infrastructure is no more than a centralised heating and cooling system such as that of any association of property owners, but on a large scale, channelled through the streets to reach every home.

The Hotel TRH Ciudad de Baeza has undertaken the remodelling of its fan-coil heating and DHW production system by installing high performance condensing boilers from the manufacturer Ygnis. The incorporation of these boilers has a very positive impact on the performance of the heating and DHW production units, as demonstrated by the consumption results obtained after two full seasons in operation. As illustrated below, the reduction in consumption brings with it a significant reduction in the hotel’s energy bill. The economic impact is such that in the space of 1.5 years, the installation investment has been paid for, taking the six-month heating period as the basis for calculating the amortisation.

The hotel had two 4,000-litre tanks for DHW, heated by four electric resistance units of 18 kW each with a total output of 72 kW. These tanks used to supply the fan-coils circuit for heating and the DHW circuit. The existing installation was located in a basement, with little available space and no flue gas outlet, thereby preventing the installation of any type of boiler irrespective of the fuel used, unless a completely new boiler room was built.

The possibility of choosing renewable sources was dismissed because the peculiarities of the TRH hotel, an ancient 16th Century Carmelite convent next-door to the Church of the Hospital de la Concepción. Its location in the historic centre of Baeza, a UNESCO World Heritage city, made any structural reform to the building completely unfeasible. The lack of flat roofs and terraces meant that it was impossible to use the rooftop for the installation of solar panels. Nor was the option of using biomass viable due to the lack of space required for its management. Read more…
