can discharge total steam produced by the boiler is

installed on the plain end. Once boiler is running in the

abnormal condition and result in super-high pressure, steam

can be discharged from safety valve.

diesel engine on the lower smoke box. On the smoke box,

there is an inspection door for overhauling.

The thermometer and barometer that lies on the upper &

lower smoke box separately can indicate the temperature and

resistance force of exhaust gas as to supervise the

In order to reduce the heat loss and insure the safety

of boiler’s running, the outer surface of boiler body and

upper & lower smoke box are covered with thick 60mm
