Note:

(1) The above working pressure is of standard boiler. Other working pressure according to order.

(2) Fuel consumption rate calculated by lump coal 5a (Hon Gai - Cam Pha) with total dry calorific value: 7900kcal/kg.

(3) Dimensions of boiler body (excluding auxiliary equipment and chimney)

Above are the parameters of standard coal-fired boilers.
Boilers with other specifications will be supplied to order.
