The 49 reported incinerators in Wuhan have been running non-stop.
There were 49 crematoriums - furnaces designed for normal use but were pushed to burn 270+ bodies a day each. There likely were furnaces that broke down or otherwise needed repairs.

There were far more bodies that admitted - but, like Tiananmen Square, those bodies are ash; the true count is an order or two of magnitude over the official count
