Coal‑Fired Boiler for Gypsum Board Plants – Engineered by a Leading Manufacturer
As a gypsum board plant coal fired boiler manufacturer, we design steam generators that meet the relentless demand for continuous, high‑temperature heat in plaster production. Our boilers deliver reliable steam at 6‑12 MPa, ensuring the drying and calcining stages of gypsum processing run without interruption, while adhering to strict environmental and safety standards.
Why Our Coal‑Fired Boiler Stands Out
- Optimized for continuous duty cycles – designed for 24/7 operation with minimal wear.
- Fuel flexibility – accepts raw coal, pulverized coal, and low‑grade blends without compromising efficiency.
- Low NOx and SOx emissions through staged combustion and flue‑gas recirculation, meeting most regional environmental codes.
- Modular construction – allows rapid on‑site assembly and future capacity upgrades.
- Full OEM/ODM support – we can integrate proprietary control panels, automatic feed systems, and remote monitoring.
Typical Specifications (customizable per order)
| Parameter | Range / Option |
|---|---|
| Steam Pressure | 6 – 12 MPa (adjustable) |
| Steam Capacity | 10 – 50 t/h (modular units) |
| Coal Feed Rate | 1.5 – 6 t/h (continuous) |
| Thermal Efficiency | ≥ 88 % (HHV) |
| Design Life | ≥ 25 years (with scheduled maintenance) |
| Control System | PLC‑based, SCADA ready, optional IoT module |
| Certifications | ISO 9001, CE, compliance with local emission standards |
How the Boiler Integrates Into a Gypsum Board Plant
The boiler sits downstream of the coal handling system and feeds saturated steam directly to the drying tunnels and calcination kilns. A typical flow is:
- Coal is crushed and delivered to the furnace via a screw or belt feeder.
- Combustion air is pre‑heated, then mixed with coal for staged burning.
- Steam generated in the boiler passes through a superheater and then a moisture separator.
- Steam is piped to the plant’s process units, with pressure regulators ensuring consistent output.
- Flue gases are treated with electrostatic precipitators and, if required, desulfurization units before stack release.
This configuration minimizes thermal losses and allows real‑time adjustment of steam parameters to match the varying moisture content of raw gypsum.
Application Scenarios
While the primary market is large‑scale gypsum board manufacturers, the same boiler platform can be adapted for:
- Calcium sulfate (anhydrite) production lines.
- Cement clinker drying tunnels where coal is the dominant fuel.
- Industrial drying processes for timber, paper, or food‑grade powders (with appropriate material upgrades).
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑spec boiler?
We accept single‑unit projects; the MOQ is one complete boiler system, which includes the furnace, steam drum, and control package. Larger orders qualify for volume discounts and staggered delivery.
Can the boiler be adapted to alternative fuels such as biomass or waste coal?
Yes. Our design includes a modular combustion chamber that can be retrofitted with a secondary burner or a fuel‑switching valve. Engineering support is provided to certify the new fuel blend under local emission regulations.
What is the typical lead time from order to commissioning?
Standard models are shipped within 15‑30 days after receipt of the purchase order and deposit. Fully customized units require 45‑60 days, depending on the complexity of the requested modifications.
Does the manufacturer provide warranty and after‑sales service?
All boilers are covered by a 24‑month warranty covering material defects and workmanship. We also offer extended service contracts, on‑site spare parts inventory, and 24 h technical hot‑line support.
