modern high pressure boilers

The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.
Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.
Automatic production line.

The welding of important parts like the vertical and circular seams of the boiler, the tubes, the inside of boiler and the flange are all adopted automated welding processes such as submerged arc welding or gas shielded welding to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.
Tube flange weld adopts robot welding.
The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.

A Study Analysis and Performance of High Pressure Boiler

Modern water tube boilers can operate at pressures in excess and generate more than 9million lb of steam per hour. Because combustion temperatures may exceed 3000°K, The water flow is controlled by natural or forced circulation .By super heaters modern boilers can achieve almost 90% efficiency.

High Pressure Boilers - High Pressure Steam Boilers These are fully water tube design boilers for high pressure steam requirements. Water circulation through the boiler may be either natural circulation due to density difference or by forced circulation.

High-Pressure Steam Cycle and Boiler Water Treatme

•Pressure range – 60-84 bar • Critical needs – High quality makeup water • External pre-treatment through distillation and mechanical deaeration – High purity steam to the turbine – No excess hydrate alkalinity – Precise control of total system water treatment High Pressure Boilers • Steam cycle

MODERN STEAM GENERATORS - Heat Engin

MODERN STEAM GENERATORS 77 Horizontal water-tube boilers with vertical or slightly inclined sectional headers having a longitudinal or transverse drum (fig.4-1), were quite popular during first quarter of the twentieth century. Now-a-days they are not built, as they can not cope up with high pressure and high duties demanded from modern boilers.

ata and above with a definite aim to generate surplus power for feeding to the grid. High pressure boilers (operating above 60 kg/cm2(g)) are normally designed close to the limiting conditions of the heat transfer, tube metal temperature, circulation etc. to make the units compact and economical. The principal problem in modern high pressure

High Pressure Boilers: Features and Advantages ~ ME Mechanic

High efficiency – High-pressure boilers have better firing methods, monitoring, furnace conditions, control flue gases and water velocity. Intensive heating – the furnace temperature in high-pressure boilers is high enough and therefore, 70% of heat is transferred to water by radiation.

This type generally gives high steam production rates, but less storage capacity than the above. Water tube boilers can be designed to exploit any heat source and are generally preferred in high-pressure applications since the high-pressure water/steam is contained within small diameter pipes which can withstand the pressure with a thinner wall.
