High Efficiency Direct Fired Thermal Oxidizer Gas Heating Precise
Temperature Control
Overview:
Direct-fired furnace is a highly efficient industrial equipment
that uses gas, oil or other combustible gases for direct combustion
and heating. It is widely used in metal heat treatment, glass
manufacturing, ceramic sintering and other fields. Its core
advantages are rapid heating, high thermal efficiency and precise
temperature control, which can meet the stringent requirements of
different processes for high temperature environments. Direct-fired
furnace has a compact structure, full combustion, and with advanced
control systems, it can significantly reduce energy consumption and
improve production efficiency. It is one of the key thermal
equipment in modern industrial production.

Product Introduction:
Solution:TO
Pollution Source:PO/HP
Capacity:13600Nm³/h
The waste gas incinerator, serving as a critical environmental
protection facility for the 300,000 t/y propylene oxide (PO)
production unit, processes 9,418–13,316 kg/h of industrial exhaust
gases generated during production. During operation, pressurized
waste gas is delivered to the incinerator burner and undergoes
high-temperature oxidation combustion in the furnace chamber,
designed to maintain a flue gas temperature of 900~1,100°C with
sufficient residence time to ensure complete combustion.
To mitigate thermal and prompt NOx emissions generated during
high-temperature combustion, ammonia injection nozzles are
installed at appropriate temperature zones, utilizing selective
non-catalytic reduction (SNCR) for in-furnace denitrification. The
heat from combustion is recovered via a waste heat boiler,
producing 9~12 t/h of saturated steam at 2.5 MPaG and 226°C. The
boiler system comprises evaporation tube bundles, an SCR reactor,
an economizer, an induced draft fan, and a chimney. After heat
recovery, flue gas is discharged through the chimney following
emission standards compliance. The entire unit occupies an area of
approximately 40 m × 25 m.
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 Direct Thermal Oxidizer (DTO) adopts high-temperature
oxidation incineration techniques, which could achieves a higher
removal rate of organic compounds.
(2) The Direct Thermal Oxidizer (DTO) can be combined with various
forms of heat recovery equipment such as reclaim steam, hot water,
hot air, and thermal oil.
(3) With versatile applications, Direct Thermal Oxidizer (DTO)can
simultaneously incinerate organic waste liquids and
high-concentration organic wastewater while treating VOCs. This
makes it suitable for various industries, including chemicals,
pharmaceuticals, and petrochemicals.
(4) Ruiding's developed Direct Thermal Oxidizer (DTO) employs low
nitrogen combustion technology, equipped with combination burners,
multi-stage air supply, and safety features such as flame arresters
and water seals. This ensures a high level of combustion safety and
comprehensive functionality.
R&D and Production:
Ruiding has established the jiangsu province clean incineration
resource engineering technology center and the key laboratory of
the JICUI-Ruidings joint innovation center.
This laboratory is equipped with advanced detection equipment such as
ICP inductively coupled plasma emission spectrometry, atomic
absorption spectrophotometry, atomic fluorescence
spectrophotometry, high-temperature combustion ion chromatography
analyzer, high-temperature combustion rate analyzer, and rapid
equilibrium flash point tester. it possesses capabilities for heavy
metal analysis, elemental analysis, off-gas calorific value
analysis, ash melting point detection, incineration boiler water
quality testing, sewage analysis, and volatile waste analysis, etc.
