THSD-IIndustrial Steam Boiler THSD-Ifor Oil- and Gasfiring

Admissible working pressure

Standard pressures: 10 and 13 bars.Higher working pressure on request.

Thermal Insulation 100 mm

The boiler is fully insulated including flue gas collector with 100mm rock wool insulation. The casing is made of structured aluminumplate, thickness 1mm. Sockets and cuttings are nicely framed.

THSD-I

Description

Delivery

The pressure body is completely insulated with a primer. Theinsulation is fixed at the factory and connection openings are raincovered. Burner armatures and control panel are either mountedon the burner or packed loosely in a separate box. Assembling ofboiler and wiring can be done at site by a local contractor resp.customer.

Industrial Steam Boiler

The Hoval high output steam boilers are made of high quality steeland are distinguished by their solid, robust and flexible construction,particularly by their operational ease, their easy maintenance andan optimal efficiency. The client receives an economical,environment friendly compact unit, ready for installation. Theboilers are constructed for oil- or gasfiring.The construction and manufacturing of the boilers is doneaccording to TRD. The local oficial approval and inspection iscarried out by TÜV or an independent test authority. The ISO 9001certification and the quality approval at our factory with our Hovalquality performance departement with works certificate guaranteethe highest product quality.

Type THSD-I E

The type THSD-I E classical 3 pass flame tube flue gas tube boilerwith an asymetric flame tube and an inner completely watercooled flue gas turning chamber guarantees high efficiency. Theboiler consists of a cylindric shell, the two headplates, the flametubeincluding the back flue gas turning chamber with water cooledfinned tube wall, the two flue gas passes and the fitting tube,placed either on the right (standard) or on the left. The burner ismounted on a fireproof plate. The boiler door is warmth insulatedand flue gas tight for burner mounting and rests hinged opposedto the fitting tube. The boiler is completely electrically welded andprovided with all required inspection openings.The spacious flame tube with low thermal charges results in anexellent combustion and reduces emissions. The large watercontent secures an even boiler running time and thus reduces thenumber of boiler starts.

On Request

- Second safety valve- Second water level meter- Second feed water pump- Modulating feed water control- Automatic boiler blow down- Flue gas Wärmetauscher

Feed Water quality

Local feed- and boilerwater regulations have to be followed andwaste water regulations have to be payed attention to. Hovalsteam boilers up to max. 22 bar.

Property colorless, clear, free of suspendedmatter and foam

pH-Value at 25°C > 9Summ of earthalkalies < 0.02 mmol/l(Ca + Mg) < 0.112°dHOxygen (O2) < 0.02 mg/lCarbon acid (CO2) bound < 25 mg/lIron, complete (Fe) < 0.05 mg/lCopper, complete (Cu) < 0.01Oil, fat < 1 mg/l

Control Panel

The electro control panel for the Hoval boiler is equipped with therequired control units and indicators for control and supervisionof boiler and burner. The operation and alarm reports are shownas fault indication. The control panel will be made upon customerrequirements and depending on burner to be used. A descriptionof the control panel display SLC 28-1 can be found on page xyzof this catalogue.

High Efficiency

Due to the above technical facts an efficiency of up to 89%, up to95% with economicer, can be achieved. Thus continuos fuel costsare kept low. The sources of energy are used more efficiently andHoval spares the environment.

Description

Delivery

The pressure body is completely insulated with a primer. Theinsulation is fixed at the factory and connection openings are raincovered. Burner armatures and control panel are either mountedon the boiler or packed loosely in a separate box. Assembling ofboiler and wiring can be done at site by a local contractor resp.customer.

Industrial Warm Water Boiler

The Hoval high output warm water boilers are made of high qualitysteel and are distinguished by their solid, robust and flexibleconstruction, particularly by their operational ease, their easymaintenance and an optimal efficiency. The client receives aneconomical, environment friendly compact unit, ready forinstallation. The boilers are constructed for oil- or gasfiring.The construction and manufacturing of the boilers is doneaccording to TRD. The local oficial approval and inspection iscarried out by TÜV or an independent test authority. The ISO 9001certification and the quality approval at our factory with our Hovalquality performance departement with works certificate guaranteethe highest product quality.

Type THD-I E

The type THD-I E classical 3 pass flame tube flue gas tube boilerwith an asymetric flame tube and an inner completely watercooled flue gas turning chamber guarantees high efficiency. Theboiler consists of a cylindric shell, the two headplates, the flametubeincluding the back flue gas turning chamber with water cooledfinned tube wall, the two flue gas passes and the fitting tube,placed either on the right (standard) or on the left. The burner ismounted on a fireproof plate. The boiler door is warmth insulatedand flue gas tight for burner mounting and rests hinged opposedto the fitting tube. The boiler is completely electrically welded andprovided with all required inspection openings.The spacious flame tube with low thermal charges results in anexellent combustion and reduces emissions. The large watercontent secures an even boiler running time and thus reduces thenumber of boiler starts.

THD-IZIndustrial Steam Boiler THD-IZfor Oil- and Gasfiring



Thermal Insulation

The boiler is fully insulated including flue gas collector with 100mm rock wool insulation. The casing is made of structuredaluminum plate, thickness 1mm. Sockets and cuttings are nicelyframed.

THD-IZ

On Request

- Second safety valve- Second water level meter- Second feed water pump- Modulating feed water control- Automatic boiler blow down- Flue gas Wärmetauscher

Description

Delivery

The pressure body is completely insulated with a primer. Theinsulation is fixed at the factory and connection openings are raincovered. Burner armatures and control panel are either mountedon the boiler or packed loosely in a separate box. Assembling ofboiler and wiring can be done at site by a local contractor resp.customer.

Industrial Steam Boiler

The Hoval high output steam boilers are made of high quality steeland are distinguished by their solid, robust and flexible construction,particularly by their operational ease, their easy maintenance andan optimal efficiency. The client receives an economical,environment friendly compact unit, ready for installation. Theboilers are constructed for oil- or gasfiring.The construction and manufacturing of the boilers is doneaccording to TRD. The local oficial approval and inspection iscarried out by TÜV or an independent test authority. The ISO 9001certification and the quality approval at our factory with our Hovalquality performance departement with works certificate guaranteethe highest product quality.

Type THD-I E

The type THD-I E classical 3 pass flame tube flue gas tube boilerwith an asymetric flame tube and an inner completely watercooled flue gas turning chamber guarantees high efficiency. Theboiler consists of a cylindric shell, the two headplates, the flametubeincluding the back flue gas turning chamber with water cooledfinned tube wall, the two flue gas passes and the fitting tube,placed either on the right (standard) or on the left. The burner ismounted on a fireproof plate. The boiler door is warmth insulatedand flue gas tight for burner mounting and rests hinged opposedto the fitting tube. The boiler is completely electrically welded andprovided with all required inspection openings.The spacious flame tube with low thermal charges results in anexellent combustion and reduces emissions. The large watercontent secures an even boiler running time and thus reduces thenumber of boiler starts.
