3 Engineering and the Contractor’s design

3.1 Employer’s design

3.1.1 SSC Process description

Coarse ash, from the boiler, falls into a bath of water contained by the SSC’s top trough structure, which

quenches the hot ash. The quenched ash is then conveyed to the front of the SSC by scrapers connected to

a chain driven system. Part of the water is removed from the ash on the dewatering slope of the SSC. The dewatered ash is then transferred by discharge chute onto one of two Coarse Ash Conveyors (CAC).

SSC performs the functions of Boiler Bottom Ash (BBA) collection, dewatering of BBA, and provides a

controlled rate of BBA discharge onto downstream plant. The SSC’s top trough correctly filled with water

working in conjunction with the dipper plates provides boiler sealing by preventing air ingress into the boiler

via the SSC.

3.1.2 Mechanical Design

SSCs are currently driven by an electro-mechanical drive system which consists of an 18,5kW electrical

motor directly connected to 3 reduction gearboxes. The output of the three-reduction gearbox is connected to

a rack and pinion gear assembly which is linked by a chain. The SSC’s drive shaft is directly connected to the

pinion gear to provide drive torque to the SSC system. This drive assembly is supplied by PIV Gearboxes and

Drives and produces 75 000 Nm of torque. The speed of the drive shaft can be varied using a variable speed

gearbox in accordance with the ash production in the boiler. The maximum drive speed of the SSC is applied

during backlog recovery conditions, refer to drawing 058/39872 in Table 13.

Figure 1: 3 gearboxes aligned to develop torque (Mechanical drive)

from losing tension and bundling under the guide idlers during operation. The chain is guided with in the SSC

by a number of idlers. Submerged idler wheels are used in the upper trough of the machines and require

adequate sealing designs to prevent water leakage from the upper trough to the outer environment. The

rotation of the idlers downstream of the tension station is monitored by the revolution of the controllers. This

device detects a breakage in the two chain strands.

motor and first reduction box. The variable gearbox has an internal hydraulic drive mechanism equipped with

an electric servo motor HDA10 AA001 (also called speed variator) with maximum and minimum speed limit

switches i.e., PIV Slip monitor relay located inside the variable speed gearbox. The speed of the SSC

conveyor chain is varied by actuating the servo unit from either locally from the IO remote panel or the unit

control room. This is done manually by the local or remote operator and is based on the unit operating load

conditions. This functionality needs to be automated in the new drive design.

The variable gearbox is also equipped with a tacho generator HDA10 CS002 which provides the feedback of

the variable speed system output to the control room in unit of percentages. The interface is via transducer

module located inside the IO remote panel. The transducer is powered through 220VAC source internal to

remote IO panel. The correct functioning of the conveyor chain is monitored through the SSC speed switch

HDA10 CS001 located on the front-end bottom chain wheel shaft as well as a slip clutch monitors HDA10

CS101/102.

The IO remote panel is equipped with push buttons (PB) related to the operation of the variable speed-box.

Table 5: IO remote panel is equipped with push buttons

2.4 Environmental constraints and management

Matimba has an Environmental Policy, PP/240/001, to which the Contractor and his employees must adhere.

• Provide sufficient storage containers, labelled depicting general or hazardous waste and store in a

designated storage area

• No hazardous waste may be stored for a period of more than 90 days on the Matimba premises
• Ensure that all hazardous waste is disposed off at a licensed Class H disposal site. A copy of the

hazardous waste disposal certificate is submitted to the Project Manager.

• Ensure that all other general waste is disposed off at the local municipal waste dump
• Ensure that the Contractor’s site does comply with the general good housekeeping practices. Redundant

materials are moved to allocated sites. No scrap shall be stored in the Contractor’s yard. Scrap is to be

cleared from Site daily.

• The non-adherence to the Matimba Environmental policy and rules could result in the termination of this

contract.

The tender is for the replacement of Submerged Scraper Conveyor (SSC) Drives Gearbox at Matimba Power Station. The SSCs are used for boiler bottom ash (BBA) and slag removal, as well as furnace sealing. The current drives have a high failure rate, long lead time, and have reached the end of their life cycle.

Mandatory: valid ECSA certification for all design engineers. Qualitative criteria: Company's capacity to execute works (40%) includes related experience (5+ hydraulic drives projects for full marks). Method statements (25%) include mechanical, electrical, C&I works. Project schedule (5%). Minimum technical score: 70%. Acceptable risks: experience related to other plant system hydraulic drives. Unacceptable risks: exclusions of scope specified in employer's requirements. Exceptions: accept deviation with technical qualification; deviation without technical qualification not accepted.

Matimba Power Station is designed to have the SSC employed underneath the boiler for the purpose of

boiler bottom ash (BBA) and slag removal, as well as furnace sealing. SSCs are driven by an input gearbox

which is directly connected to the first reduction gearbox, the variable speed drive links these gearboxes

to the electric motor. This drive assembly is supplied by PIV Gearboxes and Drives and produces 75 000

Nm of torque.

The failure rate of these drives is high and has resulted in UCLF being incurred by the station. Secondly,

these drives have a long lead time resulting in the plant running at risk when spares are exhausted, and a

failure occurs. Finally, these drives have reached the end of their life cycle, usually failing with no notice

and the condition monitoring systems onsite struggle to obtain accurate readings.
