Biomass Power

Biomass is increasingly in the news these days as it is a renewable energy source that can help thermal power plants reduce their carbon dioxide emissions. Yokogawa systems are used all over the world in all types of power plants, including those that use biomass. Yokogawa measurement and control technologies make it possible for these plants to operate more efficiently and reduce their carbon footprint.

Customer Challenge

Improving combustion efficiency and reducing/eliminating harmful stack emissions

Solution

Yokogawa oxygen analyzers measure the oxygen (O2) concentration in flue gas. With this information, the air-fuel ratio can be adjusted to optimize combustion. Likewise, our stack gas analyzers can be used to reduce harmful emissions by measuring the concentrations of nitrogen oxide (NOX) and sulfur oxide (SOX) in stack gas.

Enabling Technologies

ZR Series Zirconia Oxygen Analyzers

Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control applications and are relied on by a wide range of industries to optimize combustion and reduce NOX emissions.


SG750 Stack Gas Analyzer

The SG750 stack gas analyzer consists of an infrared gas analyzer unit, a zirconia oxygen analyzer unit, and a sampling unit, and can simultaneously measure up to five components: NOX, SO2, CO2, CO, and O2.

 

Customer Challenge

Maintaining a constant supply of steam when using a mixture of fuels

Solution

Yokogawa’s control system calculates the optimal fuel mix and adjusts the supply of fuels to stabilize the main steam pressure.

Enabling Technologies

EJX/EJA Series Pressure Transmitters/Differential Pressure Transmitters

The DPharp series of digital pressure transmitters use a differential pressure high accuracy resonance pressure (DPharp) sensor that represents one of the most revolutionary advances in transmitter technology.

Customer Challenge

The high cost of purchasing and maintaining equipment for detecting seawater leaks and ion exchange resin damage

Solution

Yokogawa’s SC450G conductivity analyzer produces output signals in two separate ranges for demineralized water management and sea water leak detection, eliminating the need for the purchase of other equipment to perform both functions.

Enabling Technologies

Contacting Conductivity Analyzers

The FLXA21 is a next-generation modular liquid analyzer that can be flexibly configured to measure pH/ORP, contacting conductivity, inductive conductivity, and dissolved oxygen. The FLXA21 also supports the installation of up to two sensors of the same type, thereby reducing installation costs and saving space.

 

Biomass Power Generation Process

Biomass plants typically are of the direct combustion, mixed combustion, or gasification type. With the direct combustion power generation method, steam is produced from the heat generated by the burning of materials such as wood waste, agricultural waste, and livestock waste. The steam turns a turbine, which in turn drives a generator that produces electricity. With this method, it is important to secure a stable supply of biomass materials and maintain a uniform moisture content in these materials. The mixed combustion power generation method relies on both biomass and coal to provide a stable flow of electricity. When insufficient biomass fuel is available to power the plant, coal is added. In the gasification power generation method, the biomass is heated to extract combustible gases, which are purified and are then used to power a gas engine or gas turbine to generate electricity.

Overview:

Facing serious environmental problems for the whole earth, clean energy using solar, wind, geothermal, tidal, etc... to reduce CO2 emissions is an inevitable matter. Renewable energy providers need economical/reliable/efficient solutions. Yokogawa provides a reliable data acquisition system with high accuracy for measurement and control instruments.

Overview:

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

Overview:

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 

Overview:

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.

Overview:

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.

Overview:

In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.
