1862 London Exhibition: Catalogue: Class I.: John Russell
310. RUSSELL, JOHN, Newport, Monmouthshire.
Steam, coking, and household coal, from Tyr Nicholas Colliery, Cwm Tylery.
The analysis of these coals will be seen on reference to a list reporting upon all coals in use for Her Majesty's Navy, as ordered by the House of Commons on the 30th June, 1858; and they will be found to stand highest for their evaporative power, and the very small quantity of clinker. These coals are now being used under contract for the navy at Portsmouth, Plymouth, and foreign stations.
The results of the experiments are as follows:-
1. The New Black Vein.
- Water evaporated for each 1 lb. of coal consumed, calculated from 100 degrees constant temperature of feed-water, 9.56 cubic feet.
- Water evaporated per hour, calculated from the same temperature, 50.67 cubic feet.
- Percentage of clinker, 0.79.
- Percentage of ash, 5.75.
They possess a high percentage of carbon with only a trace of sulphur; white ash, and are perfectly free from anything injurious to bars or boilers. Burning brightly getting up steam easily, they possess this advantage, that the small will get up steam as well as the large, and it makes an excellent coke for locomotives and all other smelting purposes.
These coals are shipped at the exhibitor's wharf, or in the very commodious docks at Newport, Monmouth, where vessels of the largest class can load at all times with perfect safety.
2. The New Rock Vein.
Analysis by Dr. Percy:—
- Carbon: 89.81%
- Hydrogen: 5.19%
- Oxygen and Nitrogen 5.0%
In the middle of this coal a live frog was found at the depth of 600 feet, March 10th, 1862.
