500 BHP Steam Boiler Price Guide – Industrial Boiler

A 500 BHP steam boiler delivers roughly 7.8t/hr of steam, serving mid-size industrial and commercial processes. Expect base equipment to cost $55 000–$120 000, depending on design, material thickness, and basic control features.

1. Base Equipment

Firetube vs. Watertube: Firetube boilers are simpler and start around $55 000, suitable for lower pressures and steady loads. Watertube designs—better for higher pressures (up to 600 psi) and fluctuating demands—approach $120 000. Materials (carbon steel vs. alloy) and shell thickness influence price within this band.

2. Emissions Control

Meeting modern NOₓ limits typically requires a dedicated burner kit. Plan for +10 % of the boiler price to cover low-NOₓ burners, oxygen-trim controls, and safety interlocks. Though it raises upfront cost, this kit often pays back via fuel optimization and avoids regulatory penalties.

3. Heat Recovery (Economizer)

An economizer captures residual flue-gas heat to preheat feedwater, costing $5 000–$10 000. Benefits include a 3–5 % fuel-use reduction and cooler stack temperatures, which extend refractory life. In high-fuel-cost regions, simple payback can be under two years.

4. Feedwater Treatment

Proper water treatment prevents corrosion and scale. A typical $7 000–$12 000 package includes a deaerator tank, feed pump skid, and monitoring instrumentation (conductivity probes, blowdown control). Skimping here risks tube failures and unplanned shutdowns.

5. Installation & Piping

Installation—foundations, flue stack, steam headers, condensate lines, electrical wiring—adds 10–20 % to the equipment price. Early collaboration with mechanical and civil contractors secures firm quotes and minimizes costly change orders during construction.

6. High Efficiency Steam Boiler (500 BHP)

Different models of 8 ton/h steam boilers produce steam at 194°C under 1.25 MPa pressure, using feed water at 20°C.
