New Boilers
Our offer includes boilers firing solid, liquid, and gaseous fuels as well as HRSG boilers.
HRSG boilers use thermal energy contained in various types of waste flue gases to produce steam or heating water. HRSG boilers are primarily used in the combined heat and power generation plants; in connection with gas and steam turbines, these boilers constitute a highly efficient source of electric and thermal heat power. Furthermore, HRSG boilers can be used for peak sources with combustion engines, in the refining plants, metallurgical plants, or compressor stations.
As far as possible, the design of HRSG boilers meets given parametric, and layout requirements.
Main features of HRSG boiler design
- Tube bundles made of finned tubes
- Gastight over-pressure vertical or horizontal design
- Boiler flue gas ducts with internal insulation and sheet casing and/or external insulation
- Duct burner integrated into the inlet flue gas duct as an alternative
- By-pass stack as an alternative
- Installation of catalyst to reduce emissions as an alternative
- Installation of noise silencer as an alternative
- Precise control of superheated steam temperature
- Compact and economical solution
- Delivery to the site in the transportable modules – minimized assembly time
- Optimized for the specific area
Several standardized boiler design options are available based on the specified parameters, and layout possibilities.
These boilers are designed to burn
- gaseous fuels (natural gas, hydrogen, blast furnace gas, coke-oven gas, converter gas, acetylene exit gases, … )
- liquid fuels (light fuel oil, heavy fuel oil, waste oils, ... )
Depending on the heated medium, the boilers are classified into two basic categories
- steam boilers with the max. steam output 420 t/h
- hot-water boilers with the max. heat output 210 MW
Main features of the boiler design
