WATERTUBE BOILERS
Fired PACKAGED watertube boilers
Rentech Boiler is known for manufacturing the most rugged and durable industrial watertube boilers on the market.
Our conservative design includes large furnaces ensuring optimum circulation, efficient heat transfer rates, and the volume required to meet the most stringent emission guarantees. All boilers are built with water-cooled, full membrane wall construction providing a low maintenance and tight gas-side seal; and steam drums designed to exceed customer requirements with high retention times, and superior steam separation internals.

D-type
Rentech’s D-type watertube boilers are the workhorse of the boiler industry!
The flexible design of our D-type boilers make it well suited for most applications. The conservatively sized furnaces are optimized to meet demanding emission levels while ensuring the longevity of your steam boiler. Superheated steam can be provided with single stage or dual stage convective superheaters, and Rentech’s super
heaters are always designed to be fully drainable.
D-type boilers are recommended for capacities from 20,000 lb/hr (9,000 kg/hr) to 600,000+ lb/hr (275,000+ kg/hr).
A-Type
Rentech A-type watertube boilers are available for applications that require large capacity, fully shop-assembled units, with difficult logistical requirements. Although somewhat limited in its design flexibility, compared to a D-Type boiler, the symmetrical design inherent in the A-Type boiler, allows for an easier shipment, via rail or truck.
A-type boilers are recommended for capacities between 150,000 lb/hr (70,000 kg/hr) and 250,000 lb/hr (115,000 kg/hr).
O-Type
Like the A-type boiler, O-type boilers are symmetric allowing for easier shipment via rail or truck. The O-type boiler is the preferred arrangement for the rental boiler industry with some units being designed with an integral trailer to allow for quick shipments.
O-type boilers are recommended when a footprint is limited up to 100,000 lbs/hr (45,000 kg/hr) steam.
Modular FIRED PACKAGED WATERTUBE BOILERS
For projects with space limitations or shipping constraints, Rentech’s team of engineers can design a modular system that includes large shop-fabricated sections that are quickly and easily assembled in the field.
