In 1984. a 1.090 MW heat recovery combined cycle power plant powered by six 701D gas turbines began commercial operation.

This was the dawn of the current era of combined cycle power generation. the DA Series incorporates F-Class technology into the D Series to improve overall performance.

Features

Integral Design

The gas turbine units are based on a basic structure adopted in the early 1970s www.abb-drive.com that has accumulated a track record of at least 40 years. Its main features are listed below:

Compressor shaft end drive reduces the effect of thermal expansion on alignment

Rotor with simple single-shaft double bearing support

Rotor construction with bolted discs, torque pins in the compressor section and CURVIC couplings in the turbine section to ensure stable torque transmission

Axial flow exhaust structure for advantages in combined cycle plant layouts

Horizontally split housing for on-site removal of the blades with the rotor in place

Compressors

The DA series utilizes high-efficiency compressors with a proven track record. The fixed vanes of the backstage are supported by vane rings to minimize tip clearance of the rotating vanes.

Variable inlet guide vanes ensure operational stability at start-up and enhance performance under partial loads in combined cycle operation.

Combustion chamber

Mitsubishi Power introduced the world’s first commercially available dry low NOx combustor to the D-Series gas turbine in 1984.

The premixed low NOx combustor consists of a pilot burner and eight main burners surrounding it. The combustion chamber has an air bypass mechanism to adjust the fuel-air ratio in the combustion zone.

Turbine

In response to the increase in turbine inlet temperature, the fixed blades of the first three stages and the rotor blades of the first two stages are air-cooled.

The rotor blades of the fourth stage are equipped with Z-shaped shrouds to enhance the vibration strength of the blades.

The fixed blades are supported by blade rings that are independent of each stage to protect the turbine housing from thermal expansion.

OVERVIEW

The IR-S type infrared flame detector is an excellent high sensitivity type that excels in “detection reliability”, “maintainability” and “economy”.

It supports boiler fuel diversity and low NOx (nitrogen oxide) operation.

By detecting the “average value” and “variation” of the infrared intensity of the burner flame light transmitted to the infrared sensor (semiconductor element) via a light guide (optical fiber), the detector can distinguish between the flame and the light due to the furnace.

The detector distinguishes between www.abb-drive.com flame and infrared light due to the red heat of the furnace wall and detects flame fluctuations in the burner’s ignition zone.

The IR-S type infrared flame detector has low brightness flame detection sensitivity and a wide dynamic range, so it can be used for a variety of fuels such as natural gas, heavy oil, and coal.

Features

High sensitivity design

High sensitivity to flame intensity enables stable detection of burner flames. Flame is detected through unlit areas.

Extended detection range

With 100 times the dynamic range of conventional products, this sensor enables stable detection of flames from slow burning to high intensity. No sensitivity adjustment of the sensor is required in the field.

Easy Maintenance

A spherical lens is used to eliminate the need to clean the sensor window during normal boiler operation.

Long Life Sensor

No periodic replacement is required due to the use of long-life infrared semiconductor sensor elements.

Fewer panels

The detector unit is compact and features a space-saving design that allows one panel to cover up to 40 corners.

Overview

In response to the need for modern monitoring and control systems in thermal power plants, the

Net IR-S infrared flame detector combines the proven IR-S type flame detector, which has been successfully installed in many power plants, with Mitsubishi Electric’s DIASYS Netmation control system.

The result is a flame detector product that can be used as a burner control system.

The Net IR-S has the same sensor unit as the conventional IR-S sensor and can be used with any of the following fuels: fuel oil, coal and natural gas.

In addition, the excellent detection reliability, maintainability and cost effectiveness of the IR-S sensor are maintained.

In addition, the decision circuitry is built as a module of DIASYS Netmation. It is used in conjunction with the upper layers of the Netmation to provide an easy-to-use interface.

The panel of the Net IR-S can be designed as a stand-alone flame detector system independent of the burner control system.

If you replace a conventional flame detector with this new flame detector, you can reuse your existing equipment.

Features

Highly sensitive design

High sensitivity to flame intensity enables stable detection of burner flames. Flames are detected through unlit areas.

Extended detection range

With 100 times the dynamic range of conventional products, this sensor enables stable detection of flames from slow burning to high intensity. No sensitivity adjustment of the sensor is required in the field.

Maintenance-free

A ball lens is used to eliminate the need to clean the sensor window during normal boiler operation.

Long Life Sensor

No periodic replacement is required due to the use of long-life infrared semiconductor sensor elements.

The detector unit is compact and utilizes a space-saving design that allows one panel to contain 40 corners.

Reuse of existing boiler facilities

The boiler itself does not need to be worked on when the flame detector is replaced.

Reuse of cables

There is no need to replace the cable between the sensor and the panel. (When UV type detection is used in an existing system)
