High Temperature Direct Fired Thermal Oxidizer Decomposition
Pollution Control Energy Regeneration
Overview:
Modern direct-fired furnaces are deeply integrated with the
Internet of Things technology, and fully automated control is
achieved through PLC or DCS systems, which monitor the combustion
status, temperature curve and energy consumption data in real time.
Users can adjust parameters through remote terminals to prevent
overload or flameout risks. This intelligent management not only
improves safety, but also reduces manual intervention, and is
particularly suitable for precision manufacturing fields that
require a stable heat source (such as semiconductor packaging and
lithium battery drying). At the same time, the fault self-diagnosis
function greatly reduces the difficulty of maintenance and
downtime.

Product Introduction:
The system is a 150,000 ton/year CHP propylene oxide project. It
adopts an integrated process of high-temperature oxidation + waste
heat cascade utilization for highly complex and high-concentration
petrochemical waste gas/wastewater (including propylene derivatives
and reaction by-products). Through the thorough decomposition of
organic matter at a high temperature of 1200°C, the membrane wall
boiler is used to recover heat to produce industrial-grade
superheated steam, achieving the dual goals of pollution control
and energy regeneration. The system is adapted to my country's
first independent CHPPO technology, providing environmental
protection technology guarantee for the extension of the propylene
oxide industry chain, and the annual steam reuse value exceeds 100
million yuan.
Waste gas treatment capacity: 40,000 Nm³/h (including complex component petrochemical waste gas)
Wastewater treatment capacity: 2.1 t/h (high-concentration organic wastewater)
Superheated steam output: 39 t/h
Steam parameters: 4.0 MPaG, 425°C (directly used in production process)
Floor area: 60m×30m (intensive module design)
Theory:
The Direct Thermal Oxidizer (DTO) first heats the combustion
chamber temperature to the set level using fuel. Then, VOCs is
introduced into and decompose into CO2 and water at high
temperatures, releasing a significant amount of heat.
Simultaneously, external equipment such as heat exchangers and
boilers recover the thermal energy carried by the purified
high-temperature flue gas to achieve energy savings and reduce
consumption.
Ruiding can comprehensively design the system based on factors such
as the airflow, composition, concentration of the VOCs to be
treated, and the desired removal efficiency. Tailored,
cost-effective VOCs treatment solutions are provided. When the
concentration of the waste gas to be treated is high enough, it's
possible to operate without fuel input. The furnace temperature can
be maintained by the self-sustaining at moderate Lower Explosive
Limits (LELs).
Advantages:
(1) The incinerator can withstand a temperature of ≥1200°C, a residence
time of ≥2 seconds, and a decomposition rate of VOCs and toxic
byproducts (such as aldehydes) of ≥99.9%. The waste gas/wastewater
synergistic treatment solves the problems of "multiphase flow, high
salt content, and easy coking" in petrochemical processes.
(2) The thermal efficiency of the membrane wall boiler is ≥85%, and
the annual steam output is ≈340,000 tons (4.0MPaG/425°C). It can
directly drive production equipment, and the annual energy saving
benefits exceed 80 million yuan. The original "economizer + air
preheater" multi-stage heat exchange reduces the comprehensive
energy consumption by 30% compared with the traditional design.
(3) The flue gas treatment adopts the combination of "bag dust removal
+ SCR denitrification", with particulate matter <10 mg/m³ and
NOx <50 mg/m³, which is better than the special emission limit.
The COD removal rate of the wastewater after high-temperature
oxidation is ≥99.5%, without the risk of secondary pollution.
(4) Fully automated control, gas consumption <3.5 Nm³/ton steam,
operation and maintenance costs reduced by 40%.
(5) Supporting the industrial application of my country's first set of
CHPPO technology, solving the environmental protection supporting
problems of propylene oxide process. The localization rate of core
thermal oxidation equipment is 100%, breaking the cross-technology
monopoly.
