SYNGAS COOLER FOR ABENGOAS FULCRUM MSW GASIFICATION

• SCHMISCHE SCHACK Scope of Supply:

• Burner

• POX

• Refractory

• RSC with Sump, CSC

• Steam Drums

• Separate Superheater with internal bypass

• Ash Handling System

• Services

• Delivery: Jan 19/ Mai 19


SYNGAS COOLER FOR COAL AND BIOMASS GASIFICATION

We delivered new additional heating surface for the TAMPA RSC in year 2006 and recently new tubes for the CSC´s

Radiant Cooler for a Coal Gasification Plant

Convective Cooler for a Biomass Gasification Plant

The Radiant Syngas Cooler (RSC) design principle put into service in 3 coal gasification.

The design concept has been developed further and today offered for several biomass and municipal waste gasification projects.


SYNGAS COOLER FOR 6 MW BIOMASS GASIFICATION

Convective Type Heat Exchanger• 1100 °C Inlet temperature• 25 g/nm³ ash from Charcoal

Main Advantage• Incorporates the lessons learned from

various syngas cooler arrangements in many gasification plants

• Avoids cost driving arrangements like complex heating surface arrangements, high alloy materials , or pure forced circulation systems

• Support and Services during and after construction and startup


SCHMIDT‘SCHE®

OVAL HEADER/ DOUBLE TUBE DESIGN

Design Principle – Double Tube

• Advantages in fire- and water tube boiler designs due to well-defined flow paths on both sides

• Intensive cooling of each tube• Straight tubes for easy gas side cleaning• Downflow minimizes creation of fouling• Low water volume for faster response to load

Special features

• Gas inlet temperature up to 1.600°C• Applicable for high gas and dust load• Resistant against erosion on tube inlet• Ferrules are not needed

SCHMIDT‘SCHE®



Gas Flow Pattern

Funnel-tube inlets guarantee an equal gas distribution into each individual tube

• Low turbulence • No gas recirculation • Limited erosion rate• No temperature peaks

SCHMIDT‘SCHE®



Steam / Water side circulation

• Lower density of the water steam mixture compared to the density of the water in the downcomer pipes drives the circulation

• The overall mass flow through the system is limited by the pressure drop in the system

SCHMIDT‘SCHE®



Design Principles – Oval Header: Flexible Member

• The oval header acts as a flexible member that compensates for the difference in thermal expansion between the inner and outer tube, reducing the mechanical stresses on the system, especially at the inlet to the transfer line exchanger.

• Mechanical and thermal stresses are reduced by using thin-walled oval header, pipes and tubes.

• thin-walled system is more flexible and temperature gradients across the wall thickness are lower.

• protecting the magnetite layer by mitigating and / or eliminating high thermal and mechanical stress
