Urduliz . LOINTEK, a leader in the design and manufacture of large industrial equipment using in-house technology characterised by its capacity to operate at high pressures and temperatures, is developing an auxiliary industrial boiler with the most flexible operating range on the current market for solar thermal power plants
On the twentieth anniversary of its foundation, the LOINTEK strategy is calling for an international presence and competitiveness on a global level. So it has committed itself towards diversifying its offer and contributing added value through the exclusive use of an in-house design in the thermal as well as mechanical aspects of the equipment. In this context the CDTI (Centre for the Development of Industrial Technology) has been collaborating in the funding of LOINTEK’s R&D projects.
Auxiliary industrial boilers for solar thermal power plants
With the backing of the CDTI, LOINTEK is developing an auxiliary industrial boiler with the most flexible operating range currently available on the market; this will allow faster start-ups and reduce the commissioning time of the boilers. What is more, the project includes a modular design feature, which considerably simplifies the assembly process, thus minimising commissioning times. In short, the new design of the auxiliary boiler offers the following advantages:
- A modular assembly that cuts down commissioning time
- A programmed cold start-up in record time.
- Boiler operation with an initial flow of 25% of capacity and from this level 100% is reached in a linear way.
No other boiler on the market currently has this operating flexibility, which gives LOINTEK a competitive advantage and a differentiated positioning on the market for this equipment.
Fast start-up auxiliary boilers for the petrochemical and industrial sector
In November 2016 LOINTEK signed an agreement with the CDTI to work on the design and manufacture of fast start-up auxiliary boilers for the petrochemical and industrial sector, and thus provide an innovative response to market demand. This project focusses on auxiliary boilers, whose core requirements include keeping them in stand-by position ready to operate at full capacity when dealing with fast hot start-up process requirements.
Right now, LOINTEK has identified a growing interest among its customers owing to the availability of the technology to keep the boilers in hot stand-by position before proceeding to fast start-up (about 10 minutes), which will allow significant operational savings to be made. The hot stand-by position is an operating mode in which the boiler is at full operating pressure and temperature but without producing any steam, which means energy consumption is virtually nil. In these conditions the boiler must be able to move on to producing full power which it is designed to achieve within a minimum time (fast hot start-up).
New software for thermodynamic design
In another of the projects backed by the CDTI new software will be developed for the thermodynamic design of shell and tube heat exchangers allowing the design of LOINTEK’s in-house baffles to be optimised. This will enable the customer’s specifications to be met with a greater capacity for response in terms of pressure drop and heat transfer, while enabling the size of the equipment designed to be reduced.
The following boiler types are among the most important equipment with respect to the products marketed by LOINTEK:
- Industrial steam boilers: main and auxiliary boilers for the energy sector, petrochemical sector and industrial boilers.
- Boilers for waste gas recovery: combined cycle.
- Thermal oil auxiliary boilers: thermoelectric and solar thermal sector.
- Cogeneration boilers.
Each suite of this equipment is designed and manufactured with different requirements in terms of pressures, temperatures, fluids, fuels and design materials adjusted to the customers’ needs.
