Introduction

The water injection valve on a steam boiler controls the amount of cooling water injected into the superheated steam in the superheater and reheater.

The amount of water injected is decisive for the temperature of the steam inside and at the output of the superheater.

Too much water injection can lead to excessive cooling of the steam, which negatively affects efficiency.

On the other hand, insufficient water injection leads to excessive steam temperature and pressure.

The risk of damage to the superheater, turbine and downstream components increases as a result.

For optimal operation of the superheater at the lowest possible steam temperature and the highest possible hot steam temperature, the

continuous and precise mass flow control of the injected cooling water is first required.

Depending on the operating conditions, this requirement means that very small amounts of water need to be supplied, thus requiring highly accurate positioning in disproportionate areas of the valve.

The operating environment is extremely harsh.

In addition, the ambient temperature in the superheater area can be very high.

Modules. As a result, economical solutions can be realized in a wide range of applications.

Economical solution.

The REG216 software system provides a library of protection functions. The following table lists the functions applicable to generator and transformer protection.

Different levels of redundancy can be selected.

The availability and reliability of the protection can be selected according to the application in the following ways

For example, the auxiliary power supply unit for the entire system can be replicated.

Standard interfaces make the REG216 compatible with different process control systems.

All hardware can be housed in a single compartment, which provides further shielding against inductive interference and physical protection against dust, etc.

All hardware can be accommodated in a single compartment, which provides further shielding from inductive interference and physical protection from dust.

The REG216 is available in 17 predefined rack configurations with a limited number of I/Os, but is equipped with the same SW library as the classic system.

Protective relays for other functions are not part of the EG216 and can be installed in compartments and interconnected with the REG216 accordingly.

Interfaces to the main system

The following modular components provide the interface between the REG216 and the power system.
