1. What is the DG Chimney Height Formula?

The empirical formula H = 14 × Q^1/3 is used to calculate the appropriate chimney height for diesel generators based on their power output. This ensures proper dispersion of exhaust gases and compliance with environmental regulations.

2. How Does the Calculator Work?

The calculator uses the empirical formula:

\[ H = 14 \times Q^{1/3} \]

Where:

\( H \) — Chimney height (meters)
\( Q \) — Generator power (kilowatts)
14 — Empirical constant
1/3 — Power exponent for scaling

Explanation: The formula provides a proportional relationship between generator power and required chimney height to ensure adequate exhaust dispersion.

3. Importance of Proper Chimney Height

Details: Correct chimney height is crucial for environmental compliance, safety, and efficient generator operation. It prevents exhaust gas accumulation and ensures pollutants are dispersed at safe heights.

4. Using the Calculator

Tips: Enter the generator power in kilowatts (kW). The value must be greater than zero. The calculator will compute the recommended chimney height in meters.

5. Frequently Asked Questions (FAQ)

Q1: Why is chimney height important for diesel generators?
A: Proper chimney height ensures safe dispersion of exhaust gases, prevents ground-level pollution accumulation, and complies with environmental regulations.

Q2: What factors affect chimney height requirements?
A: Generator power output, local topography, building height, wind patterns, and environmental regulations all influence required chimney height.

Q3: Is this formula applicable to all generator sizes?
A: This empirical formula works well for standard diesel generators, but very large or specialized units may require more detailed engineering calculations.

Q4: How accurate is this empirical formula?
A: It provides a good estimate for preliminary design, but final chimney height should be verified with local regulations and detailed engineering analysis.

Q5: What units should be used for power input?
A: Power should be entered in kilowatts (kW). If you have power in horsepower, convert to kW using 1 hp = 0.7457 kW.
