Possibility to exempt licensed operators.

Quick steam output availability, suitable for discontinuous applications.

Small footprint and compact design, both in vertical and horizontal designs.

Customized solution according to specific customer requests, especially for high-pressure applications with design pressure up to 80 barg.

Maximum efficiency that can be further improved by equipping the boilers with a heat recovery system (economizer), increasing thermal efficiency.

NOx emissions of less than 80 mg/m3 due to its optimized combination with any market burner (according to BAT).

Combustion system suitable for different fuels (natural gas, liquefied petroleum gas, diesel fuel, and hydrogen).

UM equipment complies with international standards, including PED, ASME, SELO, GOST-R, RTH, IBR, JIS, etc.

Easy maintenance: the upper cover facilitates inspection and cleaning of the combustion chamber and the internal parts of the steam generator.

UM flash coil steam generators include forced circulation and guarantee a steam production range between 500 – 4.000 kg/h. They can be supplied both in vertical or horizontal models, fully packaged and with all the necessary equipment to be connected with site utilities.

UM-HP series are steam generators of the natural circulation type. The coil is manufactured in 16 Mo3 to guarantee a long life for the boiler even in challenging working conditions, with pressure steam up to 100 barg and temperatures up to 312°C. The coil’s dimensions, large furnace, low thermal load, and low-pressure drops ensure steam circulation already at low pressure.

Customized solutions are possible for high-pressure applications, especially in terms of design pressure up to 80 barg.

These steam generators are manufactured in-house on our dedicated line for seamless, perfect production of pipes and spirals.

Water forced by a piston pump is circulated through pipes forming the heating surface, which is divided into three sections for:

• Preheating of feedwater
• Conversion of water into steam
• Slight superheating of steam to reduce water content

UM steam boilers are supplied in standard and container versions.

Ideal for special applications, such as edible oil refineries, UM-HP boilers are fully customized and tailored to the customer’s needs.

Demineralization plant

Boiler water feeding requires low hardness concentration and conductivity to reduce the blow-down (heat loss). Two different types of treatment can be used: membrane-based technology and ionic-exchange solutions. Dedicated pre-treatments are necessary, based on the available water source.

Deaerators

It is necessary to remove CO2 and O2 to prevent corrosion phenomena. There are two options available: conventional packages composed of a tower and a drum, or the compact “smart” unit where the degassing equipment is realized inside the drum. The performance range is 7-20 ppb, according to the type of the installed unit.

Condensate treatment

It is necessary to purify the steam condensate from the process, to reduce water consumption and recover the heat contained in the condensate.

Dosing of chemical products

Oxygen scavengers are used as the protective dosage downstream of the thermo-physical degassers and as the alkalizing agents to maintain a high pH inside the boiler. The choice of proper water treatment represents the energy optimization of the steam generator/water treatment package and a source of savings in water extraction and discharge costs.
