  • Remotely controllable
  • Automatic fuel fed
  • Generates grid spec electricity for grid or behind the meter consumption
  • Capable of generating
  • 45 kWe (avg.) electrical power at 0ºC
  • 130 kWt (avg.) thermal hot water at 0ºC
  • Able to offset approximately 360 tCO2e per annum (can offset more if landfill diverted syngas is burnt with biomass fuel)
  • Easy to install
  • Easy to service
  • Minimally environmentally invasive
  • Emissions are fractions of EU and Alberta allowable limits

Introduction

The CHP13045 Biomass Generator is a carbon neutral electrical heat and power unit delivering approximately 45 kWe and approximately 130 kWt.  Fully automatic CHP13045s are revolutionary and a cost effective alternative to diesel and traditional generated power.  The CHP13045 units are purpose designed.  They combine transportation industry components, thermodynamic engineering expertise and 30 years of practical Biomass combustion experience in a robust cost effective energy system.  The CHP13045 efficiently converts the calorific energy stored in biomass, into thermal and electrical power.

The CHP13045 is an environmentally conscious, easy to operate solution that fits the need for GHG neutral CHP systems.  Proven and in production, the CHP13045 requires minimal maintenance or operator involvement under normal working conditions.  It is designed to be used at maximum continuous power without manual intervention, except for bunker re-fueling and ash removal.  Regular maintenance is scheduled quarterly and a complete maintenance is scheduled annually.

Installation requirements

Building Requirements

In severe climates CHP13045 should be installed:

  • Inside a well-ventilated enclosed section of a building
  • Inside a well-ventilated separate boiler-house

In moderate climates CHP13045 could be installed in an open walled building such as a Dutch Barn that would keep weather off the CHP13045.

Footprint

CHP13045s require:

  • A flat level concrete base 16 m by 6.44 m with access to the outer walls and roof for air intake and exhaust respectively
  • A 24 tonne rating for the base

Electrical Connection

The CHP13045s electrical power criteria:

  • 72k VA 3-phase
  • Automatic phase matching and grid synchronization (600V, 3 phase, 60Hz)
  • Power factor of 1

The CHP13045 is designed for export power, behind the meter use and can be configured to deliver stand-alone power.

Water System

CHP13045s require plumbing as specified on plumbing connection drawings for a thermal heat dissipation system that takes 80⁰C water at 108 liters per minute and 3 bar (plumbing standard) and can dissipate up to 150 kWt of unused heat and returns 60ºC water at up to 108 liters per minute.

Fuel Use

The CHP 13045 uses fuel at the approximate rates identified in the following table.

Moisture Content (%) Burn Rate (Kg per hour)
10% – 20% 60
20% – 40% 75
41.50% 95

Operators should note that fuel burn rate depends on many factors such as the quality of the fuel, temperature of fuel going into the combustion chamber, type of wood, etc., in addition to moisture.  The figures presented here reflect testing on EU G50 resinous wood chips with moisture content indicated.  Testing of wood chips with 62.5% moisture content demonstrated that a running CHP13045 is able to operate using “fresh-cut-woods”.  Operators should note that fuel use increases as moisture content increases.

  • Either in line the combustor feed auger
  • Or at a right angle to the combustor feed auger
  • The distance from the bunker to the rotary valve can be 5m
  • The slope of the bunker auger can be no more than +/- 10⁰

Fuel Size

Wood chip size and distribution must meet Ecological Standard M7133:

Standard    % by weight of relevant chip size (mm)     Extreme Values (mm)
  20% max 60-100% 20% max 4% max Cross section Length
EU G50 >31.5 31.5-5.6 5.6-1.0 <1.0 50 95


Servicing

The heat exchanger requires a monthly cleaning and oil and oil filter must be changed every quarter.  A major service is required after 30,000 hours.
