1. The horizontal coal-fired hot water boiler is a single-drum vertical type in structure. Water wall pipes are installed on the left and right sides of the furnace to form a wing-shaped flue. Threaded smoke pipes are arranged in the boiler. The movable grate has a reasonable structure and high thermal efficiency, which greatly saves energy consumption.
2. Horizontal coal-fired atmospheric steam boiler, hot water boiler, gas boiler, oil-fired boiler, coal-fired boiler, energy-saving and environmentally friendly boiler, adopts a three-pass water-fire tube structure with a single drum longitudinally arranged, and the two sides of the furnace are densely distributed with light pipes and water-cooled wall tubes. The structure is reasonable and compact; the heating area is large, the flue gas flow is long, the heat transfer effect is good, and the flue gas temperature is low, so the thermal efficiency is high, the operating cost is low, and the use is more economical.
3. Vertical coal-fired boilers and hot water boilers. The furnace adopts a water-cooled elbow structure. The furnace is surrounded by a furnace. The heating area is large, the thermal efficiency is high, energy saving and consumption reduction; the shell adopts oval head, and the grate adopts cast iron round grate , Durable and long service life.
4. Horizontal coal-fired boiler. After the fuel is burned on the grate, the flame passes through the low wall to the burning chamber, from the burning chamber to the front smoke box through the wing-shaped flues on both sides, and then from the smoke tube bundle to the rear smoke chamber. Then it is drawn by the induced draft fan and discharged into the atmosphere through the chimney, which not only prevents the bottom of the boiler shell from being radiated by the high temperature of the furnace, but also reduces the temperature of the flue gas at the entrance of the high temperature tube sheet. It can effectively prevent the tube sheet from fouling due to overcooling and boiling, and the furnace bottom convex hull. The flue gas can be turned to the flue chamber to remove dust and reduce the original dust concentration

5. The coal-fired boiler has a compact layout, small floor space, convenient transportation, quick-installation and delivery, short installation period, low installation cost, low user investment and quick recovery benefits.

 6. Vertical coal-fired boilers, hot water boilers, and all the pipes in the heating area are straight pipes, and there are enough hand hole devices for cleaning dirt, which is convenient for manual and mechanical cleaning of dirt and internal inspection. The horizontal coal-fired atmospheric hot water boiler is equipped with a large enough manhole on the upper part, and personnel can enter the inside of the furnace through the manhole, which greatly facilitates the inspection and maintenance of the boiler.
