COMBINED HEAT & POWER - Cogeneration


Wellons Combined Heat and Power facility

SMART GRID, SMART PRODUCTION

It's more important then ever to generate electrical power as inexpensively and efficiently as possible. One proven way to accomplish this is with a Wellons cogeneration system. Generating electricity and simultaneously satisfying plant process steam requirements is not a new idea, however the viability of such systems is more apparent than ever. Cogeneration from wood waste just makes good sense in today's energy conscious world.

Wellons Cogeneration Benefits Include:

  • Low cost evaluation of the proposed project, including specific State and Federal incentives for which your project may qualify.
  • Ongoing assistance with permitting, contract negotiation, interconnection, grants/loans, etc.
  • In-house engineering and manufacture of system components for better control of project schedule and cost.

SYSTEM COMPONENTS


The Boiler

Our modular boiler is engineered for factory pre-assembly of major components to reduce installation time. The design is specifically tailored for compatibility with the wellons cell furnace, assuring optimum system performance.

Our field-erected boilers, designed to be fired by the wellons cell furnace system. Provide the greater steam flow, higher pressure and the higher temperatures needed for power plants.

Wellons' approach to lower emission levels starts with preventative measures taken at the furnace where formation of gaseous pollutants begins. Through efficient combustion design and precise control of air and fuel in each cell, gaseous emissions and particulates are kept at minimum levels. Secondary pollution control devices are often unnecessary. Learn More »

The Turbine-Generator

Wellons selects the size and type of turbine-generator according to stringent specifications. We are experienced with small backpressure turbines and larger condensing turbines as well as the condensing-extraction units typical of cogeneration systems.

When appropriate, Wellons will locate and procure used turbine-generator equipment suitable for the project. Our service includes removal and storage, technical direction, and complete repair and reconditioning; as well as electrical and mechanical inspection and testing.

Used turbine-generator equipment is totally dissassembled, inspected in accordance with Wellons' high standards, repaired as needed, aligned, reassembled, and then thoroughly tested.

Furnace Cells

The Wellons cell furnace system's unique firing process not only maximizes efficiency through complete combustion and precise air control, but also provides positive benefits to the elimination of pollutants such as particulate, nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic compounds (VOC).

Wood gasification occurs on water-cooled grates where most non-combustibles are collected for convenient access and easy removal. Both stationary and Wellons patented, automatic ash discharge. Rotary grates are available.

The Wellons cell is used in multiples, creating a zoned furnace system in large boiler applications. Precise control of each cell in the system allows direct control of the combustion process.


Wellons Switch Yard

The Switchgear

Wellons designs and installs all necessary electrical switchyard equipment for interconnection with the local utility. This vital link is another example of Wellons' commitment to eliminating potential incompatibilities by offering a complete turnkey operation.

Fuel Storage & Handling

The Wellons storage bin is an important element in making our systems truly automatic. It is unsurpassed in fuel handling. Unique in the industry, the Wellons agitator saws its way around the periphery of the cone, feeding the loosened material down to the feedout augers below. The silo section is designed with a negative slope so that fuel materials do not hang up on the side walls. All mechanical conveying equipment is simple and effective keeping power consumption at the lowest possible levels. Learn More »
