Tuabine installation Project Project: Vung an thermal power plant A. Introduction

Vung ang thermal power plant build in the Vung ang zone, ky anh district, Ha tinh province. It consists of two units with a capacity of 600 MW per unit (2x600MW). The owner is Vietnam Oil and Gas Group, the equipment supplers Toshiba Janpan. Viet nam LILAMA Erection Coporation is the general contractor EPC, assigned the task of processing, manufacturing , installing, test run without load and load of equipments. In there, LILAMA 69-1 is responsible for installation of Tuabine-Generator and additional equipments related Tuabine – Generator is a high-pressure turbine, condensing pure with intermediate steam superheating. Tuabine includes three parts, high-presure part, medium presure part, low presure A and low presure B are supported on the bearing numbers 1, 2, 3, 4, 5, 6. Tubine is operated and protected by electro-hydralic system to ensure safety in all turbine operating regime I. Base compiled

1.1Base on the explanatory drawings, tubine-generation installation instructions, take condensing type VA1-TSB-00M-M-M1B-MAN-8000 1.2 Base on the explanatory and technical drawings of installation of tubine and generator number 0KS00201-0KS002014. 1.2 Base on the documentation of Tubine – generator installation test Record. II. Brief introduction of specifications of Turbine.

2.1. Turbine-generator are provided by Toshiba Japan, every unit with 600MW capacity, Turbine is a condensing pure type with three parts( high presure, medium presure in the same body, low presure A and low presure B in the separated body)? 󰁍󰁥󰁴󰁨󰁯󰁤 󰁳󰁴󰁡󰁴󰁥󰁭󰁥󰁮󰁴 󰁯󰁦 󰁉󰁮󰁳󰁴󰁡󰁬󰁬󰁡󰁴󰁩󰁯󰁮 󰁔󰁵󰁲󰁢󰁩󰁮󰁥

- Installation of diaphragm laminate must comply with the process, hoist gently, before installing, every diaphragm laminate adjusted to meet requirement for the clearance and contact, should continue to install the next diaphragm laminate. - Adjustment of diaphragm laminate’s centre and altitude. Use A micrometer gauge, seal, feeler gauge to check ad adjust the clearance, asembly, bolt installed and secured by a torque wrench or hammer or lock against rotating. 2.20. Put on the lid of turbine’s high- pressure

- Specifications of the equipment in the cylinder checked, (attached checked documents). - Clean, check the dimension of keyhole, assembly tabs, apply white-lead on the surface. - Cover use a bridge crane on the engine compartment, pulley, cable, specialpurpose shackle, attach to cable (as the figure No.19), hoisting up about 1000mm, check cable, the safety of hoisting device, in the same time, istall 4 pilot-pins into turbine’s lower part. Use mechnical level balance the cylinder, when ensure the safety conditions to continue to hoist the cylinder into the position. - The cylinder is near the position, far from the flange about 250mm, stop to clean the upper assembly surface and lower assembly surface, after that apply the colloidal film for the assembly surface and continue to get down until 2 flanges touch together.
