Zirconia oxygen analyzer

1Overview:

Zirconia oxygen analyzerMainly used in industries such as thermal power plants, waste to energy plants, steel plants, chemical plants, etc., the main working principle is based on zirconia oxygen concentration batteries, which convert the oxygen content of flue gas into potential signals at high temperatures. The product features real-time, online, high-temperature direct measurement, fast response, and high accuracy. CE-2C typeZirconia oxygen analyzerIt belongs to the split flange installation direct insertion zirconia oxygen analyzer, which monitors the oxygen concentration of flue gas online.

2、 Application of the product:

Power industry:

Thermal power plants (coal-fired boilers): Boiler, circulating fluidized bed, gas turbine flue oxygen monitoring, usually using direct insertion flange installation, CE-2C type, wall mounted LCD display.

Function: Adjust the air-fuel ratio, improve combustion efficiency, reduce coal consumption, decrease exhaust emissions, and optimize production.

Supporting: DCS/PLC automatic air control, achieving low oxygen combustion

Selection:CE-2C-ISG-1000 Zirconia Oxygen AnalyzerWall mounted, LCD display, output 4-20mA, range: 0-25%.Direct insertion flange installation, insertion depth: 1000mm, flange specification: DN50

Steel metallurgy:

Blast furnace hot blast stove, steel rolling heating furnace, coke oven, sintering machine flue

Function: Control the atmosphere inside the furnace, reduce oxidation and burn/decarbonization, increase hot air temperature, and save coke

Scenario: Leak detection of all hydrogen heat treatment furnace, research and development of thermal storage burner

Selection: Steel plants and metallurgical industries mainly use high-temperature extraction zirconia flue gas analyzers, which can monitor the oxygen concentration of flue gas online in the range of 0-1600 degrees.

Petrochemical industry:

Catalytic cracking regenerator, ethylene cracking furnace, hydrogenation unit, flare gas

Function: Control oxygen, prevent catalyst sintering, improve selectivity of epoxyethane, and ensure process safety

Selection: The explosion-proof direct insertion zirconia oxygen analyzer selected adopts explosion-proof design.

Building materials/kilns:

Cement kiln, glass kiln, ceramic kiln, tunnel kiln

Function: Stabilize kiln temperature, improve product quality, reduce energy consumption, and control emissions

Selection: Due to the high temperature of the flue gas, which is usually greater than 700 degrees, we use a high-temperature extraction zirconia flue gas analyzer that can monitor the oxygen concentration of the flue gas online in the range of 0-1600 degrees. We use a high-temperature three-way valve, jet pump, and wall mounted LCD display.

Environmental Protection and Solid Waste:

Garbage incineration, hazardous waste incineration, RTO/CO incinerator

Function: Convert emission concentration (based on benchmark oxygen), meet environmental networking requirements, and support carbon accounting data.

Selection: Due to the presence of corrosive gases in the flue gas, we use corrosion-resistant zirconia probes, which can effectively reduce measurement errors and shorten the lifespan caused by corrosion.

3、 Selection and installation points:

Select according to operating conditions: constant oxygen (boiler/flue, 0-25% O ₂), trace oxygen (inert gas/protective gas), explosion-proof type (chemical/hazardous waste)

Installation: Insert directly into the flue/furnace, tilt the probe downwards to prevent dust accumulation and condensation, equipped with blowing and anti blocking measures

Advantages: High temperature resistance (600-1600 ℃), fast response, maintenance free, long service life
