Fully Automatic Corner Tube Boiler Intelligent Control Durable Earthquake Resistance

Fully Automatic Corner Tube Boiler Intelligent Control Durable and Low Consumption

Overview:

Corner tube boilers use large-diameter downcomers at four corners to replace the traditional steel frame structure, forming a self-supporting frame system with strong earthquake resistance and a 30% to 50% reduction in floor space. The steel frame-free design not only reduces material costs, but also simplifies the installation process, making it particularly suitable for industrial scenarios with limited space, such as chemical plants and paper mills.

Product  Introduction:

This ‌50 t/h medium-temperature, medium-pressure gas-fired boiler‌ features a ‌natural circulation system‌, ‌single drum design‌, ‌horizontal flue passage‌, ‌longitudinal drum arrangement‌, ‌full membrane wall structure‌, and ‌slightly pressurized combustion‌‌.Key design features are as follows:
(1) Steam Pre-Separation & Drum Connection‌:Top connecting pipes of the water tube system link to the lower header via ‌vertical risers‌, directing pre-separated steam ‌above the drum water level‌ to prevent submergence during evaporation‌.
(2) Steam Drying & Separation‌:Steam passes through ‌integrated separators‌ (e.g., cyclone separators, corrugated plate separators) above the drum water level, achieving ‌≥95% steam dryness‌‌.
(3) Tubular System & Thermal Balance‌:A fully welded network of ‌connecting pipes, headers, and water-cooled walls‌ employs ‌synchronous expansion design‌ (aligned with drum expansion) to neutralize thermal stress‌.Insulated pipes and headers require ‌no additional maintenance‌‌.

Technical Specifications:

Advantages:

(1) ‌‌Structural innovation‌: 

Four-corner large-diameter downcomers are used to replace traditional steel frames to form a self-supporting frame system with strong earthquake resistance and 30%~50% less floor space‌;

‌(2) ‌‌High-efficiency heat transfer‌: 

Fully enclosed membrane water-cooled walls cover the furnace and flue, and with the flag-type heating surface structure, the thermal efficiency can reach more than 92%, and the exhaust temperature drops to below 120℃‌;
‌

(3) ‌‌Flexible adaptability‌: 

Supports multiple fuels such as oil and gas, and the single unit capacity covers 10~220 tons/hour steam or 7~160MW hot water.

(4) Special Boiler R&D Capabilities‌:

With A-class boiler manufacturing qualifications and environmental engineering general contracting qualifications, we possess design experience in special boilers such as waste incineration boilers and pyrolysis furnaces. We can customize corner tube boiler systems for treatment of salt-containing wastewater and chemical waste gas. Our modular design supports rapid expansion (with steam capacities ranging from 5 to 200 tons/hour), reducing installation cycles by 40% and operation and maintenance costs by 30%.

(5) Material and Process Breakthroughs‌:

We utilize nickel-based alloy-coated membrane water-cooled walls that can withstand flue gas temperatures of ≤1200℃, improving sulfur compound corrosion resistance by 2 times and extending service life to ≥15 years. The carbide silicon-lined combustion chamber reduces erosion and wear from high-temperature flue gas on the boiler body.

‌(6) Engineering Experience and Intelligent Operation and Maintenance‌:

We have participated in large-scale projects such as the CNOOC-Shell Polycarbonate Project and the Guangzhou Petrochemical Waste Heat Renovation Project, with a single project steam capacity reaching 1500kW. Dynamic Acquisition of Boiler Operation Parameters；
Enhanced Fault Prediction Accuracy；40% Reduction in Lifecycle O&M Costs.

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.
