Recently ZBG had one set of 10 ton natural gas fired boiler shipping to Bangkok, Thailand, which is going to be put into operation in a rubber tire processing factory. This set of steam boiler proper system inludes boiler proper, valves and instruments, economizer; auxiliary equipment include water feeding pump, flectrical control cabinet, steam header, burner (Baltur Italy), automatic water treatment, deaerator (10t/h Matched including deaerator pump,control cabinet).
In fact, over the last months, there were several gas or oil fired boilers ordered by customers from different industries, but I find that most of them are water tube type boiler. So why more customers choose water tube boiler?
High efficiency (generally greater than 85 %) hence reduced fuel consumption.
Flexibility of design – important space consideration.Capable of high output (i.e. high evaporation rate).
High pressures and temperatures improve turbine plant efficiency.
Flexible in operation to meet fluctuating demands of the plant – superheat control rapidly responsive to changing demands.
Generally all surfaces are circular hence no supporting stays are required.
Steam can be raised rapidly from cold if the occasion demands (3 to 4 hours compared to 24 hours for smoke tube or fire tube boilers) because of the positive circulation.
Consider a fire tube or smoke tube boiler and a water tube boiler with similar evaporative rates the water tube boiler would be compact and relatively light by comparison and its water content would be about 7 tonnes or less compared with the smoke tube or fire tube boiler’s 30 tonnes.With double casing radiation loss can be cut to 1 % or less.
