Solar steam generators
SUNCNIM designs, builds (EPC) and operates solar steam generators (SSG) for heavy oil production and process industries
Principles
- CSP (Concentrated Solar Power) solar systems produce thermal energy (heat) through the use of mirrors. These systems focus solar radiation on a receiver
- SUNCNIM has designed its own technology based on Fresnel mirrors. Several rows of slightly curved mirrors reflect the sunlight onto a fixed receiver tube called absorber. Water circulated through a pump is injected into the absorber and then heated by the concentrated sun’s rays
Some questions ?
The main advantages of SUNCNIM's technology
A simple and robust technology to provide the lowest cost of steam
Simple, robust, modular
- Direct steam generation
- Fixed receiver
- Reflector made with flat glass mirror
Cost effective
- Lowest cost of CSP technology for construction & operation
- Use of standard materials
- Fully automatic patented cleaning system with very low water consumption
High local content
- Mobile workshop on project site to manufacture the reflectors
- Contribute to local economic development and job creation
- Standard materials easy to purchase locally
Main characteristics of the SUNCNIM module:
- Dimensions: 67m x 18m, height 9m; 900m2 of mirrors,
- Thermal energy output characteristics : water or saturated steam from 1 to 120 bars,
- One driving actuator per module,
- Modules assembled in lines (typically up to 500m), and lines in parallel,
- Unit peak power: approx. 500kWth/module
Performances
SUNCNIM guarantees the annual energy production of the solar steam generator through simple indicators in order to monitor the level of performance. This performance guarantee is valid throughout the entire duration of the project: development phase, provisional and final acceptance of the system and normal operation by the customer. Our guarantee is based on the proven proprietary calculation software on operation in the CSP demo plant in la Seyne-Sur-Mer since 2010
Fraunhofer ISE validated the thermal performance of SUNCNIM demonstrator in La Seyne sur Mer based on thermal in-situ measurements of test sequences in summer 2015
SUNCNIM is a member of the R&D EU program STAGE-STE which aims to define the future disruptive improvement of CSP technology.
Local content
CNIM has designed and developed its solar technology taking into account the specificity of the target host countries. This development choice enables SUNCNIM Fresnel technology to have a strong local content compared to other CSP technologies
The components involved are simple; materials are low cost and commonly used on most markets. Furthermore, due to the simple design, the assembly and erection of the solar plant is directly carried out on site using temporary workshops thus creating local jobs close to the erection site
These features allow the CNIM technology to be a vector of energy development while guiding and encouraging local suppliers in the development of the local industry
