Overview

LSH vertical coal-fired steam boiler adopts mainstream combustion technology. Coal is input from the furnace door and burned on the grate. High temperature flue gas is flushed through horizontal water pipes in the furnace and enters the flue gas combustion chamber. Through high-temperature radiation, the flue gas and smoke are fully combusted twice, and the heat is fully absorbed and utilized before being discharged into the atmosphere. It is smoke-free, environmentally friendly, and energy-efficient

Product Details

The LSH vertical coal-fired steam boiler adopts a new combustion technology, in which coal is input from the furnace door and burned on the grate. High temperature flue gas is flushed through horizontal water pipes in the furnace and enters the flue gas combustion chamber. Through high-temperature radiation, the flue gas and smoke are fully burned again, and the heat is fully absorbed and utilized before being discharged into the atmosphere. It is smoke-free, environmentally friendly, and has high energy-saving efficiency. (The company introduced * and achieved)

performance advantage

The curved water pipe arranged on the upper part of the furnace body is the convective heating zone, and the grate pipe and furnace liner arranged on the lower part of the furnace body are the radiation heating zone. The furnace structure and flue gas flow are arranged reasonably, with good heat transfer. The boiler design is reasonable, the structure is simple, the operation and maintenance are convenient, the footprint is small, and the infrastructure investment is low. It is one of the ideal equipment for small enterprises and institutions to produce steam, heating, etc.

1. Compared with traditional vertical boilers, this furnace has a larger heating area, faster heating and pressure rise, less coal consumption, and higher thermal efficiency, which can save 25-30% of biomass fuel.

2. One furnace is versatile and convenient for users. The steam produced by this furnace can be used for steaming meals in the cafeteria, disinfecting tableware, heating bathhouses, producing steam, and heating local rooms.

3. This furnace adopts natural ventilation, does not require blowers or induced draft fans, and has no noise.

4. Compact structure, easy installation, operation, and maintenance, can be transported as a whole, suitable for mobile units.

5. Heating baths, food, heating, steaming rice, etc. with steam, the pressure gauge scale should be strictly controlled within the design pressure, and the working pressure should not be exceeded at any time.

working principle

A coal-fired steam boiler consists of main pressure bearing components such as the head, drum, top of the furnace chamber, furnace chamber, and bent water pipe.

The boiler grate is placed on the upper part of the U-shaped lower foot inside the furnace chamber, and the flame directly flushes the furnace chamber and the curved water pipe installed inside the furnace chamber; The structural characteristics of a vertical curved water tube boiler are: an internal curved water tube is installed inside the furnace chamber, which increases the radiation heating area. However, due to the high degree of water cooling in the furnace, the furnace temperature decreases accordingly, making it generally suitable for burning high-quality coal. If refractory bricks are added to the furnace to maintain a high furnace temperature, poor quality coal can also be burned. The water circulation is good, and all parts washed away by smoke are cooled by water, resulting in good elasticity of the entire structure.

The combustion section adopts a double-layer grate combustion chamber, which heats up and boosts the pressure quickly. The unburned gas undergoes secondary combustion to achieve complete combustion, smoke reduction, and dust removal.
