I. composition and function of water vapor sampling analysis device

The water vapor sampling analysis device consists of high temperature high pressure rack and instrument sampling disk, which can realize the continuous sampling of condensate, water supply and steam, and analyze water quality index and manual sampling online.

The high temperature and high pressure rack is used for the decompression and precooling of each circuit sample, ensuring the safe and reliable operation of the instrument sampling rack.

Instrument for real-time sampling frame test samples of water quality of each circuit, and the local display and remote transmission to the control instruction and data storage, remote transmission signal is also involved in chemical dosing system of automatic control, alarm and interlock.

High temperature high pressure stand

Inlet isolation valve - cooling - depressurization - constant pressure - constant current

   ▲ Inlet isolating valve

- High temperature and high pressure needle control valve

- Maximum pressure of 38MPa

- the highest heat resistance of 650 ℃

- material S31608

- The valve tip adopts high temperature alloy steel

- The valve tip adopts a ball of semi-spherical high temperature resistant material

Precooling device

- After initial cooling, the life of the high temperature drain valve can be extended effectively. Reasonable distribution of cooling load reduces cooling water consumption.

- Double layer stainless steel coil, reverse convection heat exchange, cooling area 0.4 m2.

- cooling water into the jellyfish tube and out of the jellyfish tube to prevent the phenomenon of "snatch water", ensure that all water pipes have the same cooling efficiency.


The composition and function of the chemical additive device

Chemical dosing system by adding ammonia unit, add hydrazine unit, add oxygen and other components of the unit and the furnace protection dosing unit, including plus oxygen and units by oxygen bomb, bus frame, high and medium pressure valves, pressure reducing valve, relief valve, check valve, etc, and other units by the chassis, metering box, mixer, metering pump, valve, control box and pipe accessories, etc.

The function of the chemical dosing system is to be able to control the condensate water system such as circulating cooling water, water supply and the parameters such as PH, oxygen content, limit the heating system piping and equipment of metal corrosion and fouling, guarantee thermal system can be safe and reliable operation of equipment.
