Preparation of feasibility study for alternative fuel systems for Kiln No. 1 following its modernization on the plant of Dyckerhoff Polska sp. z o.o.

 

 

1. Project description

 

Preparation of feasibility study for alternative fuel systems for Kiln No. 1 following its modernization.

 

Starting from the next couple of years, Nowiny Cement Plant is expected to increase its cement sales and then production. Considering strategic European Union ambition goal on fossil-CO2 emission reduction, then reducing carbon footprint of the products while keeping competitiveness, it would be required to add RDF in the combustion of the existing 4000 tpd kiln line and revamped to be operated once again.

The additional RDF would need additional footprint for RDF storage, same as conveyors, weight feeder dosing systems, fan, blower and electrical motor, Vecobelt, pneumatic pipelines and burner modifications; consisting in an upgrade of the current installation. As follows, there is the indication of the area of Nowiny Cement Plant subjected to modifications within the Cement Plant.

            RDF is today already used during the combustion of the other kiln line to reduce fossil CO2 emission. In fact, RDF has a biomass content that produces bio-CO2 emissions (generating a net emission) and it has also a specific calorific value due to the plastic content. This allows to burn a greener fuel compared to the common fossil fuel. Also, burning RDF in a Cement Plant has shown to be a virtuous example of waste valorizations, which otherwise would have been burnt in incinerators without any heat valorization.

 

2. Subject of the request for proposal

 

The subject of this request for proposals is:

 

1. 1. Preparation of feasibility study for the installation of alternative fuel systems for kiln No. 1 following its retrofit.

 

In Appendix 16.2 of the request for tenders, the flowsheet of the existing RDF plant is shown with the new additional RDF plant for the 4000 tpd kiln line. Particularly, from the existing “STELA DRY BELT”, RDF is split and conveyed to the new RDF “Hi-grade” plant. [see attached document 3] Two types of RDF fuels will be used. Hi-grade RDF fuel will be managed by the new installation (blue colour in the flowsheet), and it will be burnt in the headed kiln (8.4 t/h) and in the precalciner (1.8 t/h). Lo-grade will be managed by the existing installation (pink colour in the flowsheet), and it will be burnt in the precalciner only (18 t/h). Dosing system is designed to exchange routes to vecobelt or pneumatic systems in case of faults. Same as Lo-grade, the Hi-grade will be equipped with a heavy fraction separator that has also the function of flash dryer for drying the RDF from the moisture content. The flash dryer of the Hi-grade and Lo-grade will be fed by hot air coming from the grate clinker cooler coming from the 4000 tpd kiln. Existing Stela-dry belt (grey colour in the flowsheet) will be modified by receiving hot air from clinker cooler coming from the 4000 tpd kiln only.

 

Equipment required with the upgrade new installation RDF split to the new RDF plant The upgraded new installation is composed by the following equipment units:

• 1x Truck docking and unloading station
• 3x Belt weigher equipped with dust filters
• 2x Fans
• 2x Hoppers
• 1x Bridge Crane
• 1x Disk screen
• 5x Screw conveyors
• 3x Scraper redler conveyor
• 1x Blower to convey RDF to the head burner
• 1x Heavy fraction separator + flash dryer
• 1x Slide gate damper
• 1x Vecobelt
• Several RDF sample collection points along the plant for quality monitoring

 

Moreover, since more RDF is needed to be burnt, additional storage of RDF is required.

 

Process data:

Upgraded RDF configuration will be able to increase the total substitution rate in the main burner up to 90%.

• Additional storage of RDF will be 5000 m3.
• Flowrate of additional air used to convey RDF will be 4500 Nm3/h.
• Flowrate of hot air from grate clinker cooler going to Hi-grade headed kiln: 4500 Nm3/h
• Flowrate of hot air from grate clinker cooler going to Hi-grade precalciner: 2250 Nm3/h
• Flowrate of hot air from grate clinker cooler going to Lo-grade headed kiln: 3600 Nm3/h
• Flowrate Hi-grade RDF fuel burnt in the headed kiln (8.4 t/h)
• Flowrate Hi-grade RDF fuel burnt in the precalciner (1.8 t/h)
• Flowrate Lo-grade RDF fuel burnt in the precalciner only (18 t/h)

Process Control, Sensors & Automation Equipment units will be equipped with sensors for continuous monitoring & controlling process parameters and to meet quality requirements. Also, RDF sampling points are envisaged for discontinuous quality controls from lab analysis. Process will also be conducted by PID regulators and all the automations required for continuous adjustments of process parameters to keep set points.

 

Documentation must be delivered both digitally and hard copy.

The following elements will be considered when evaluating a bid:

1. 1. 1. Net order price (A) – weight: 100%,

The final score is the total number of points for each criterion. The bid with the highest final number of points will be considered the most advantageous.

 

9.2.1 Order price (A) (max 100 points):

The value of the bid should include all costs according to item 6. that the Contracting Authority will have to bear in connection with the performance of the subject matter of the contract.

The price to be evaluated will be the total net price (excluding VAT) for the execution of the order.

The price of the subject of the contract can be only one – no variants of bids are allowed.

       Methodology for awarding points:

            The number of points (A) (max 100 points) for the tested bid will be calculated according to the following formula:

A= (bid price at which the lowest net price among the evaluated bids was indicated)price listed in the bid under review*100%

 

 

 

1. 3. Final grade

The bid that receives the highest number of points calculated according to the following formula will be considered the most advantageous. The selection of the Contracting Authority is final and not subject to appeal or complaint.

Scoring criteria
