Most heavily designed and built boiler in its class. Welded Steel Firetube boiler, the LPE has extra-heavy 12-guage tubes for extended life.

All tubes are attached to the tube sheets by rolling and flaring. There are no welded tubes in the LPE. Thickest Materials used in the industry Boiler Shell is 5/16″ thick boiler plate 20-40 HP. Twin boiler tube sheets are 1/2″ thick boiler plate. Insulation is 2″ mineral wool and is lagged with 22 gauge boiler jacket.

Extra heavy 4″ channel iron boiler skids. OXYMISER Feedwater Deaerators. Removes carbon dioxide as well as oxygen. Raises the boiler feedwater temperature, eliminating thermal shock in boilers. Improves overall boiler room efficiency. Feedwater pumps are sized for each individual application – assuring total compatibility and optimum operation.

Vessels are ASME Code constructed for 50 psig. Compact design means smaller boiler room requirements. Integrated Monitoring and Control Systems are available for all Deaerator and Feedwater options Call P.C. McKenzie Company for all of your Hurst Boiler Part Needs. Natural Gas for Our Future Natural Gas an ideal fuel source for many reasons, including safety.

Natural Gas is lighter than air. This means that it will not puddle (like gasoline) or sink to the ground like propane, which is heavier than air. Instead, Natural Gas will rise and dissipate in the atmosphere. Natural gas also has a higher ignition temperature.

This means that it is much harder to ignite. Also the storage systems used for compressed natural gas are infinitely stronger that the gasoline tanks found on cars and trucks today.

Inspection Access. The waterside openings are located in the most effective positions. The lower handholes offer far better access for both cleanout and inspection. These more functional locations avoid the obstructing handhole “tunnels' used by our competitors.

The top opening offers a strategic view of the furnace crown sheet. More Steam Storage.

Capacity to handle swing and spike loads – quick recovery - quick response. The larger steam-release surface is calmer, reducing carry over of unevaporated water.

The resulting drier steam also reduces system scaling. In addition, dry steam helps to eliminate unnecessary extra condensate. Energy and fuel are saved. Longer life results.

Four-Pass Design. The gases leaving the furnace are split four ways and travel through four individual serpentine fin passages to the stack outlet. Each quarter of the heat travels its own four-pass path (see illustration below). Heat transfers evenly to the fins and boiler shell, eliminating the metal stress due to uneven heat transfer common in other designs. This illustration shows the progression of four gas paths around the circumference of the boiler shell. Primary-pass in furnace pipe. Second-pass follows path through fins along outside of shell.

Third-pass follows path through fins along outside of shell. Fourth-pass follows path through fins along outside of shell, then merges together to exit exhaust stack. Options and Alternatives. We specialize in customizing your boiler. The Cyclone can be equipped to suit a wide variety of installations and specifications. We will help direct you to the most cost-effective models and features.

Simple Installation. Unit is skid mounted for easy handling. Factory wired with wiring schematic included in the manual.Efficient and space saving layout. Available Accessories. The Cyclone is available in a complete package with an optional compact boiler-mounted feedwater system for a finished wired and piped, ready-to-fire unit. Blowdown separators are also available. Turbulent Flame.

Heat is forced down, with the fire whirling and spinning against its natural flow. This pattern enhances recirculation, mixing and heat transfer, driving more energy into the water for greater fuel-to-steam efficiency. Reliability. The furnace crown is water cooled, eliminating troublesome refractory breakdown inherent inunits of inferior design. No fire tubes, water coils or “in the fire' mud rings to burn out. 'Eye High' Burner. No step ladder is needed to service.

No bending over or sitting on the floor. The air intake is located in the center of the unit so dust is not pulled from the floor. Durability. Fire does not pass under the bottom mud ring, eliminating the blistering that occurs with other designs.

Cooler furnace gases are located at the bottom of the vessel where scale is most likely to occur. Baking of scale is alleviated. Easier Service. Fireside fin access in top and bottom. Access opening above feedwater inlet for easy cleaning. Thoughtfully engineered with the owner in mind. No heavy doors or covers to complicate service procedures.
