Utility Boiler

With over 40-year history on manufacturing utility boiler, HBG now is one of the largest utility boiler manufacturers in China. The main production of coal-fired utility boiler, coal slurry, coal ganue, coal water slurry, blast furnace gas and other fuels. Combustion techniques include pulverized coal combustion, grate combustion, fluidized bed and circulating fluidized bed combustion. Through the introduction of absorption of advanced technology at home and abroad, starting from a high starting point, we become the main supplier of domestic utility boilers and our products are used throughout the country.

Pulverized Coal (PC) Fired Boiler

Product Features

1、With excellent performance on load adjustment and combustion management, satisfying the variation range of coal property from low-quality bitumite to lignite;

2、Adopting the new composite multi-function & low-Nox horizontal bias burner;

3、With excellent stable combustion performance at low load;

4、Effectively preventing coking, high temperature corrosion and assuring the full combustion of pulverized coal;

5、Effectively improves reliability of boiler parts and operation availability.

Blast Furnace Gas (BFG) Fired Boiler

Product Features

1、High efficiency :dual swirling burner and refractory lining in combustion area, to ensure high combustion temperature; ower excess air coefficient and sealing furnace completely to ensure over 88% heat efficiency.

2、Simplified burner, air&gas system:self-developed dual-swirling BFG burner, arranged in front wall (for 75-180t/h), or front & rear wall(over 200t/h), each burner has capacity upto 2.5x10Nm/h,effectively simplify boiler system for easy operation and maintenance, and save investment cost.

3、Turn-down ratio: low-load stable combustion, minimum 25% of load could be achieved with pure BFG combustion by reasonable arrangement of the self-developed dual-swirling BFG burner and refractory lining in combustion zone.

4、Fuel Flexibility:BFG,COG,LDG,NG,or even HFO can be mixed together for combustion.

5、Reasonable heating surface arrangement:evaporation convection heating surface can be arranged in proper location to reduce economizer outlet boiling degree; spiral fin tubes can be used on economizer to increase maintenance space.

Circulating Fluidized Bed(CFB )Boiler

1、High & large furnace design,Prolonging the coal partiches’troughput time in furnace,to effectively reduce the carbon content of fly ash and manage the combustion condition;

2、Involute cyclone wish high separating efficiency, lining internally with abrasion-proof material fixed by intensive metal pins, to realize the quick start-up&shut-down and save the cost of refractory material;

3、Carbon content of fly ash less than 8%;

4、Turn down ratio 30%;

5、Typical nozzle type and proper nozzle arrangement, to discharge the large-particle ash slag in time;

6、Adopting reliable abrasion-proof structure for rear heat surface,to effectively minimize the contradict between abrasion and soot formation;

7、Multiple optimized design to prevent from abrasion and coking, reliable sealing and expansion system setting etc., to assure the performance parameters and structure of boiler.
