Injection cooler - Desuperheated steam coole 5751 -7010

Product catalog summary

Introduction: The document outlines technical specifications and installation guidelines for the MDK and PDK series of injection coolers and desuperheated steam coolers, used for precise steam temperature control in industrial settings.

Specifications:

Available in electrical (MDK 5351, MDK 5451) and pneumatic (PDK 6351, PDK 6451) series.
Features include selectable control characteristics, precise steam temperature control, a turndown ratio of 30:1, and optimal atomization starting at a pressure differential of 5 bar.
Constructed with housings made from A 106 Gr.B and A 335 P11 materials, with internal parts containing at least 13% chromium steel.

Function Description:

Designed for situations where steam conditioning valves are limited or unsuitable, especially with significant variations in steam flow or injection requirements.
Operates by injecting finely atomized cooling water into the steam flow post-pressure reduction, maintaining steam temperature at least 5°K above the saturated steam temperature.
Utilizes twist nozzles for optimal mixing and cooling effect, with the number of nozzles adjusted based on operational data.

Installation Guidelines:

Requires a mounting flange on the pipe with a minimum height of 150 mm between the flange and the pipe.
The nozzle head should align with the steam flow direction, and the cooling water connection can be configured according to structural specifications.
A straight, unbranched pipe section is necessary after the desuperheater for adequate evaporation, with a minimum length potentially up to 20 meters.
The cooling medium must be free from contamination to prevent clogging or damage.

Actuators:

Electric actuators are detailed in data sheets 5116-7010 and 5106-7010, while pneumatic actuators are covered in data sheet 6100-7010.
Configurations with other brands are available upon request.

Dimensioning Parameters:

Data required for sizing and selection of the injection cooler is provided, ensuring compatibility with specific operational requirements.

Technical Specifications: The document outlines necessary data for sizing a desuperheater, including mass flow rate of steam at the inlet, steam pressure, inlet steam temperature, steam temperature after cooling, cooling water pressure, cooling water temperature, and pipe inner diameter.

Calculation Procedures: It details the calculation of the cooling water quantity and the Kv-value, which is the flow coefficient. The calculations involve parameters such as the density of cooling water, mass flow rate of cooling water, and enthalpy values for inlet steam, outlet steam, and cooling water. The pressure difference between cooling water and steam pressure is also considered.

Material and Component List: The document provides a comprehensive list of materials and components for different models of injection coolers and desuperheated steam coolers. It includes the designation, quantity, and material for each component, such as nozzle heads, nozzles, twist disks, piston rings, seals, bushings, housings, cones, spindles, bonnets, flanges, pipes, and nuts. Recommended spare parts are also highlighted.

Key Components and Materials: Components are made from various materials like 15Mo3, 13CrMo, X2CrNiMo17-12-2, and graphite. Specific models such as MV 5351, 5451, PV 6351, 6451, and their variants are mentioned with their respective material specifications.
