Modular Combustion Control System

Product catalog summary

Overview: The document discusses the Modular Combustion Control System (CCS) developed by Hitachi Zosen Inova, designed to enhance the efficiency and automation of waste incineration plants. The system aims to provide tighter control over combustion processes, leading to improved stability and efficiency.

Key Features:

Modular Design: The CCS is customizable with additional modules to meet the specific needs of modern waste incineration plants.
Automation: The system allows for extensive automation, ensuring reliable and largely automatic operation even with changing fuel characteristics.
Control Quality: The CCS improves control over important process parameters, resulting in uniform combustion, stable steam generation, and reduced component stress.

Modules:

Module 1: Detects and stabilizes the fire position on the grate by adjusting local variables.
Module 2: Enhances fuel feed consistency by analyzing waste properties and resistance coefficients.
Module 3: Analyzes combustion processes and waste quality over time, identifying causes of load fluctuations and initiating countermeasures.
Module 4: Computes the calorific value of primary combustion gas and moisture content of waste fuel based on flue gas analysis.

Primary Control Objectives:

Maintain a constant steam flow rate as defined by the operator.
Keep the volumetric combustion air flow rate constant.
Ensure complete gas burnout by stabilizing oxygen concentration in the flue gas.
Operate the plant close to the optimal operating point while considering process limits.

Advantages: The CCS provides a volumetrically constant combustion air supply, which is crucial for effective flue gas treatment. It also offers intuitive operation, allowing easy adjustments to optimize the combustion process.

Modular combustion control system Tighter control – extensive automation – greater efficiency More steam for your plant The new combustion control system (CCS) developed by Hitachi Zosen Inova provides increased control quality for all important process parameters. The advantage for your plant: controlled and uniform combustion, stable steam generation, reduced component stress, and less fouling of the combustion chamber. Combustion is the heart of every waste incineration plant. The behaviour of related processes such as flue gas treatment and the water-steam-cycle depends heavily on the stability...

Automatic, reliable, constant The new CCS lets you make the most of your plant because it enables reliable and largely automatic operation at the required load point. Even while fuel characteristics change, control interventions proactively prevent steep drops in steam generation, and at the same time assure sufficiently high combustion chamber temperatures as well as complete gas and slag burnout. A major advantage is the concept of the volumetrically constant combustion air supply and thus volumetrically constant flue gas flow rate. This benefit should not be underestimated, especially for...
