To determine the percentage of daily operational costs that can be covered by the $38,400 saved from using concentrated solar power (CSP) to preheat the furnace for silicon production, we need to calculate the total daily operational costs of silicon production.

===== The total operational costs include: =====
# Energy Costs for Silicon Production: - This is the primary target for savings using CSP.
# Raw Material Costs: - Cost of sand (silica) and reducing agents (like carbon).
# Labor Costs: - Wages for workers and technicians involved in the production process.
# Maintenance and Overhead Costs: - Costs for maintaining equipment, facilities, and other overheads.

===== Let's consider each cost component in detail: =====

====== Using conventional energy sources, the energy requirement to produce 1 ton of silicon is approximately 12 MWh. For 64 tons (the daily processing capacity aided by CSP), the total energy requirement is: ======

Total Energy Required=64 tons×12 MWh/ton=768 MWh/day\text{Total Energy Required} = 64 \, \text{tons} \times 12 \, \text{MWh/ton} = 768 \, \text{MWh/day}Total Energy Required=64tons×12MWh/ton=768MWh/day

With an electricity cost of $0.05 per kWh:

Energy Cost=768,000 kWh/day×$0.05/kWh=$38,400 per day\text{Energy Cost} = 768,000 \, \text{kWh/day} \times \$0.05/\text{kWh} = \$38,400 \, \text{per day}Energy Cost=768,000kWh/day×$0.05/kWh=$38,400per day

This is the amount saved by using CSP, as calculated earlier.

====== Assuming the following prices: ======
* Silica (sand): $50 per ton.
* Carbon (reducing agent): $300 per ton.
* Other additives and materials: $100 per ton of silicon produced.

For producing 64 tons of silicon per day:

Cost of Silica=64 tons/day×$50/ton=$3,200 per day\text{Cost of Silica} = 64 \, \text{tons/day} \times \$50/\text{ton} = \$3,200 \, \text{per day}Cost of Silica=64tons/day×$50/ton=$3,200per day

Cost of Carbon=64 tons/day×$300/ton=$19,200 per day\text{Cost of Carbon} = 64 \, \text{tons/day} \times \$300/\text{ton} = \$19,200 \, \text{per day}Cost of Carbon=64tons/day×$300/ton=$19,200per day

Cost of Other Materials=64 tons/day×$100/ton=$6,400 per day\text{Cost of Other Materials} = 64 \, \text{tons/day} \times \$100/\text{ton} = \$6,400 \, \text{per day}Cost of Other Materials=64tons/day×$100/ton=$6,400per day

Total raw material cost per day:

Total Raw Material Cost=$3,200+$19,200+$6,400=$28,800 per day\text{Total Raw Material Cost} = \$3,200 + \$19,200 + \$6,400 = \$28,800 \, \text{per day}Total Raw Material Cost=$3,200+$19,200+$6,400=$28,800per day

====== Assume the labor cost is $10,000 per day for a medium-sized silicon production facility. ======

====== Assume these costs are $15,000 per day, covering equipment maintenance, utilities, administrative expenses, etc. ======

===== Sum up all these components: =====

Total Daily Operational Cost=Energy Cost+Raw Material Cost+Labor Cost+Maintenance and Overhead Cost\text{Total Daily Operational Cost} = \text{Energy Cost} + \text{Raw Material Cost} + \text{Labor Cost} + \text{Maintenance and Overhead Cost}Total Daily Operational Cost=Energy Cost+Raw Material Cost+Labor Cost+Maintenance and Overhead Cost

Substituting the values:

Total Daily Operational Cost=$38,400+$28,800+$10,000+$15,000\text{Total Daily Operational Cost} = \$38,400 + \$28,800 + \$10,000 + \$15,000Total Daily Operational Cost=$38,400+$28,800+$10,000+$15,000

Total Daily Operational Cost=$92,200 per day\text{Total Daily Operational Cost} = \$92,200 \, \text{per day}Total Daily Operational Cost=$92,200per day

===== Now, calculate the percentage of total daily operational costs covered by the $38,400 savings from using CSP: =====

Percentage Savings=($38,400$92,200)×100%\text{Percentage Savings} = \left( \frac{\$38,400}{\$92,200} \right) \times 100\%Percentage Savings=($92,200$38,400)×100%

Percentage Savings≈41.63%\text{Percentage Savings} \approx 41.63\%Percentage Savings≈41.63%

===== Using CSP to preheat the silicon production furnace can cover approximately 41.63% of the total daily operational costs. This significant savings highlights the potential economic benefit of integrating CSP technology into the silicon production process. =====

By reducing reliance on conventional energy sources, you not only lower operational costs but also enhance the sustainability and environmental friendliness of the silicon manufacturing process, which is crucial for expanding the production of solar-grade silicon.
