Greenfield Specialty Alcohols Inc.

Chatham, Ontario

Heat connection between the technical room from Greenfield Specialty Alcohols Inc to the heat delivery point from Truly Green behind the streetway of Bloomfield road.

Between the Truly Green Greenhouse delivery point and the technical room a transportation pipe line DN400 is installed. The piping will be mounted subsoil in pre-insulated piping, including 4 extra up-risers for a connection with the cold water towers.

Between the cold towers a transportation pipe line DN400 is installed.


 

The design of the heating installation is based on the greenhouse surface area of 68.161,5 m².

We deliver and install 1 traditional 3 pass boiler, make: Crone and a 2000 m³ hot water storage tank including nitrogen expansion system.

The existing boiler room is prepared with a manifold and spare connections for the new phase. The new greenhouse project consists of a total of 8 climate zones with a central walk way and a pack house. In the greenhouse each climate zone is provided with a tube rail with gable heating system behind the outside gables. The grow pipe and upper heating system is divided in 4 separate controlled sections system. The greenhouse heating installation consists of:

Tube rail heating (10 x Ø51x2,4 mm) Grow tube heating (10x Ø38x2,1 mm) and a upper heating (4 white powder coated tubes Ø35x1,2 mm per 9 meter trellis and gable heating.

Also the greenhouse is provided with a CO₂ dosing installation connected to the flue gas condensers of the gas fired boilers in the boiler room.

Cooling installation

The total design of the cooling installation is based on the greenhouse surface area of 5.152 and future phase of 5.376 m². The design is based on a cooling capacity of 185 w/m² with closed screens. 

Near the new cooling technical room we will place a Carrie double chiller on a concrete foundation.

In the technical room we’ll build a manifold Ø 508 mm. for the two departments. One connection for the current mixing group and one connection for the future connection.

In the technical room we delivered and placed an expansion vessel with a volume of 2.000 ltr. The expansion vessel is based off the volume from the storage tank with an average temperature of 30 °C.

In the greenhouse we placed 16 cool units for cooling the greenhouse temperature.

In the technical room the steel piping, pumps, valves will be insulated with 19 mm armaflex and cladded with 0,6 mm smooth aluminum plate.

The outside steel piping will be insulated with 19 mm armaflex and 50 mm. wol and cladded with smooth plate same color as the cladding of the tank.

Delivery and installation of a vertical hot water storage tank with a capacity of 2.500 m³ and a cylindrical height of 12,50m. For the expansion of the water in the heat storage tanks we supply and install a nitrogen generator expansion system.  Boiler installation modification to open buffer system.

Storage tank and pipelines are insulated.  Water treatment boiler installation.

Water treatment:

  • Water softener
  • Partial flow filter DSF50
  • Lubron 217D (water treatment to stabilize calcium and magnesium salts in order the minimize boiler scale – minimize oxidation corrosion and forming a corrosion resistant film on the metal surface.)
  • Lubron 401 (water treatment added to the intake water to raise the pH of the water.)

The design of the heating installation is mostly based on the greenhouse surface area of four production phases each with a surface of 42.228 m².

The manifold and transport lines are prepared for four phases. The heat storage tank is prepared for two phases. The greenhouse project phase 1 consists a total of 4 climate zones with a central walk way and corridor. In the greenhouse, each climate zone is provided with a tube rail and gable heating system behind the outside gables. The grow pipe heating system is divided in 2 separate controlled sections. Phase 1 is also provided with a CO₂ dosing installation connected to the flue gas condenser of the gas fired boiler in the boiler room.

Heating installation Chicken Farm

The boiler room installation is designed for 3 boilers of 100 kW. In the farm we installed 5 air heaters. Installation includes a transport group with 2 stainless steel tubes for the supply and return.
