COAL-FIRED BOILER
Traditionally, coal-fired boilers were the conventional choice, utilizing coal, coal fines, and wood as fuel. However, significant advancements have been made in recent years, including improved designs, advanced manufacturing technologies, automated control systems, enhanced safety features, and integrated water heating equipment. Additionally, these boilers are often equipped with cyclone dust collectors, wet scrubbers, and sulfur removal systems.
① Static Chain Grate Coal-Fired Boilers
The static chain grate coal-fired boiler is a cornerstone in METTECH’s product line, offering a reliable solution for steam output ranging from 150 kg/h to 4T/h. These boilers feature a standard configuration that includes comprehensive dust treatment, water treatment systems, and chemical dosing pumps to enhance operational stability, extend lifespan, and meet stringent environmental standards.
The WV model static grate coal-fired boiler is a vertical coal-fired boiler, so the capacity is limited to a range of 0.15-0.75 tons/hour. However, it is extremely space-saving, compact, and simple to operate. Designed and manufactured by METTECH for units using small amounts of steam heat, it contributes only a small part to the production line. Therefore, it will not be equipped with fully automatic systems like high-end products with larger capacity but ensures that the initial investment cost, maintenance cost, and labor will be significantly lower.
As the model with the largest size and capacity in the static grate coal-fired boiler product line, Model KE still retains the same principles and operating methods as Model E. Capacity is only about 3–4 tons/hour, suitable for customers who use a moderate amount of steam but still save on investment and labor costs.
Technical Parameters
Fuel Used
METTECH has carefully calculated and researched the design to launch a line of static coal-fired boilers, suitable for coal, with a calorific value of 6500–7500 kcal/kg. Additionally, the boiler can be used in combination with firewood to save costs if there is a source of firewood available during production.
Structure
● All three product lines of static coal-fired boilers designed by METTECH optimize the natural circulation of water in the boiler, with many improvements in cleaning doors and ash doors for convenient maintenance and repair.
● The combustion chamber is designed to be large to create the best burning space for fuels, reduce smoke and dust, and save fuel.
● Cyclone dust filter system combined with a wet dust filter (stainless steel filter) ensures environmental standards.
Key Advantages of Static Chain Grate Boilers:
◈ Space-saving, compact designs suitable for small-scale operations.
◈ Flexible fuel options for cost savings.
◈ Optimized combustion chamber for fuel efficiency and reduced emissions.
◈ Enhanced maintenance features, ensuring long service life.
② Chain Grate Coal-Fired Boilers
For larger capacity needs, METTECH’s chain grate coal-fired boilers excel with capacities ranging from 4T/h to 30T/h. Designed and manufactured by Hai Phong Boiler - METTECH, these boilers integrate advanced automation and fuel-saving technology to optimize performance.
With outstanding advantages such as automatic operation and fuel cost savings, the chain grate coal-fired boiler is an optimal choice for large steam capacity ranging from 4T/h to 30T/h. Equipped with advanced equipment configurations such as cyclone dust collector, desulfurization equipment, water treatment equipment, degassing soft water tank, air dryer, water heater to utilize exhaust heat, automatic fuel feeding, and slag discharge, chain grate coal-fired boilers dominate the current boiler market.
Technical Parameters
Structure
● Combustion chamber: The chain grate structure burns fuel on the grate surface moving along the furnace. Coal feeding equipment and mechanical slag discharge ensure stable operation. A strong, evenly distributed air supply system allows adjustments at different locations for optimal combustion. The special refractory material structure ensures reliability in harsh environments.
● Steam chamber: Includes two balongs arranged along the furnace body and a combination of fire tubes, water tubes, or natural circulation water tubes, depending on the furnace capacity.
● The boiler features a water heating system and air drying to maximize the heat of exhaust smoke, improving fuel efficiency.
● Cyclone dust filter system or fabric bag dust filter combined with wet dust filter (stainless steel filter) ensures compliance with environmental standards.
Advantages of Chain Grate Boilers:
◈ Automatic operation for ease of use and lower operating costs.
◈ High-capacity output suitable for heavy industrial operations.
◈ Durable construction to withstand harsh environments.
◈ Comprehensive emission control systems ensuring environmental compliance.
◈ Uses cheap fuel and has low operating costs (automatic), making it suitable for large capacity.
