Product Introduction:

The boiler is a ‌vertical membrane wall boiler‌ with a ‌single steam drum design‌. Its main structure is arranged vertically from top to bottom as follows‌:
(1) Steam Drum‌: Fixed at the top of the rear steel frame‌
(2) Membrane Wall Radiation Section‌: Primary component for radiative heat transfer‌
(3) Superheater‌: Multi-stage tube bundle layout to enhance convective heat exchange‌
(4) Five-Stage Economizer‌ (No. 1–5): Counterflow arrangement for optimized waste heat recovery‌

Core Component Features:
(1) Membrane Wall‌:Executes ‌radiative heat transfer‌ as the main functional unit‌;Exhibits ‌high-temperature resistance‌, ‌corrosion resistance‌, and ‌structural sealing‌‌
(2) Superheater‌:Utilizes ‌multi-stage tube bundles‌ to improve convective heat transfer efficiency‌
(3) Five-Stage Economizer‌:Counterflow design‌ maximizes residual heat recovery and reduces flue gas temperature‌

Advantages:

(1) ‌Structural Innovation‌:

It employs a membrane water-cooled wall to replace traditional refractory furnace walls. The metal wall surface directly absorbs radiant heat, reducing the furnace body's weight by over 30% and enhancing airtightness, thereby reducing heat loss from exhaust gas due to air leakage.

(2) Professional Customized Design‌:

Membrane water-cooled walls can be configured in various forms, such as the double-cylinder membrane wall structure (SZS type), which shortens the installation period by 40% and reduces the steam cost per ton to less than 130 yuan.

A skid-mounted mobile boiler solution is available, suitable for temporary energy supply or distributed energy scenarios.

A panel-mounted boiler solution is also provided, suitable for medium to large boilers.

‌(3) High-Temperature Resistant Material Technology‌:

The high-temperature section of the membrane wall is surrounded by high-quality refractory materials, withstanding smoke temperatures up to 1200°C and improving corrosion resistance by 2 times, with a service life of 15 years or more.

It is equipped with a silicon carbide-lined combustion chamber, reducing direct erosion of the furnace body by high-temperature flue gas.

‌(4) Intelligent Control and Operation & Maintenance‌:

It integrates a PLC control system and IoT module, providing real-time monitoring of wall temperature, pressure, and combustion efficiency, with a fault warning accuracy rate of 98% or higher.

Supports remote adjustment of combustion parameters, dynamically matching production loads, and reducing comprehensive energy consumption by 12% to 18%.

Applcation:
Suitable for high-temperature and high-pressure scenarios such as industrial waste heat recovery, large-scale central heating, and chemical production. Single-unit steam capacity ranges from 10 to 200 tons.

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.
