Shipping Container Boiler House

This shipping container boiler house conversion, started out as a once used 40ft high cube container (40ft x 8ft x 9ft 6in). Our first job was to cut and shut this container down to the required 30ft length. Below is a step-by-step guide to the complete conversion process, to house a biomass boiler. As always we start with a CAD drawn up to our client’s exact requirements.

Our client required their shipping container boiler house needs to be 30ft long. To achieve this non-standard length we use the cut and shut method.

Step 1 – Cut and shut

This involves making two cuts behind both sets of corner posts on a 40ft container. This means that all four corner posts are retained when the container is welded back together, for maximum strength when lifted.

Step 2 – Cutting roof aperture

A 2.5m long aperture is cut across the entire width of the container, ready for the top box construction.

Step 3 – Cutting apertures for personnel door and vents

First we cut the apertures, then we add the frames, ready to hold the vents (two either side), and the personnel door.

Step 4 – The roof box

The next job is to manufacture the top box for the roof. We constructed a frame using steel box section, and then filled in with steel panels cut to the required size – our client has requested the top box to fit the aperture we cut into the roof earlier, therefore must be an exact size of 2.4m wide x 2.5m long. The roof box is required with a sloping height of 61cm falling to 56cm.

Before we mount the top box, we have to make apertures for four louvered vents.

Once we have mounted the top box into place, the main structure of the container conversion is complete.

Step 5 – Repainting

The interior of the container is repainted first, in grey, and then we prepare the outside of the container, for repainting in green. This requires masking the areas that don’t need any surplus paint on them, including the door frames, locking gear and vents!

Step 6 – Fitting the vents

After repainting we can add the final touches – the 500mm louvered vents (with rodent mesh) into the main container and the top box.

We can convert containers to house boilers to any required specifications. To view another example of this type of conversion, take a look at this project completed as a boiler plant room for a building development company.
