Prominent Features
• D type water tube, 2-pass mud drum and upper steam drum design makes it possible to work with high efficiency in high pressure systems.
• Design, production and commissioning can be carried out with economizer and steam superheater unit upon request.
• The heating surfaces are clear and true values. The total area of heat transfer in the boiler is given clearly and accurately.
• Provides safe and stable operation thanks to high quality safety equipment.
• Thanks to PLC controlled touch screen control panel, quick technical support can be obtained from anywhere in the world with easy operation and remote access from mobile devices.
• Shipped with long-lasting insulation that minimizes heat losses.
• Large and sufficient combustion chamber allows the efficient use of different types of gas and liquid fuels.
• Optional integrated superheater application can be made.
• Consists of combustion chamber, membrane wall type, water tube sections. The smoke travels between the convection heat transfer section, which consists of bundles of tubes, and is fed out through the side flue outlet channel.
• Production in accordance with EN12953 and PED2014 / 68 CE directive
• Welding control of our boilers is carried out with ULTRASONIC test within the scope specified in EN 12953.
• After the boiler tubes are fixed to the boiler mirror with roller expander, welding process is applied. Thus, the risk of cracks in welds due to thermal stresses occurring in boiler tubes is eliminated.
• Our welded productions are carried out by certified welders according to approved WPS and WPQRs. Automatic submerged arc welding, MIG-MAG and SMAW welding techniques are applied in accordance with the norms.
• They are manufactured by using high quality, certified boiler sheet and seamless boiler tubes in accordance with standard requirements.
