1. The design and manufacture of coal-fired hot water boilers/coal-fired heating boilers/coal-fired bathing boiler boilers/coal-fired bath boilers are strictly in accordance with “Safety Supervision Regulations for Small and Atmospheric Hot Water Boilers” and JB/T7985-2002 “Small Boilers” The requirements of “Technical Conditions for Atmospheric Hot Water Boilers” and “Technical Conditions for Manufacture of Shell Boilers” are strictly implemented.

2.The boiler is designed according to the normal pressure, and the top of the furnace body is equipped with an atmospheric opening, the boiler runs without pressure and the combustion operation is safe and reliable. Atmospheric hot water boilers can be installed wherever they are used, and they are not restricted by the various levels of annual supervision and inspection procedures, so they have developed rapidly in recent yea

3.Vertical coal-fired atmospheric hot water boiler, mainly composed of shell head, furnace bladder, furnace roof, lower sealing ring, cupola and horizontal water pipe. The combustion chamber is arranged in the furnace, and the fuel is burned on the fixed grate for natural ventilation. The flue gas is scoured horizontally through the horizontal water pipe in the furnace bladder, and is discharged into the atmosphere through the cupola and chimney.

4.Vertical coal-fired hot water boiler, the furnace adopts a water-cooled elbow structure, surrounded by a furnace, with a large heating area, high thermal efficiency, energy saving and consumption reduction; the shell adopts an oval head, and the grate adopts a cast iron round grate, which is durable Durable and long service life.

5.The horizontal coal-fired hot water boiler is a single-drum vertical type in structure.

6.The horizontal coal-fired atmospheric hot water boiler adopts a three-pass water-fire tube structure with a single drum longitudinally arranged. The two sides of the furnace are densely arranged with light pipes and water-cooled wall pipes. The design structure is reasonable, 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.
7.For vertical coal-fired atmospheric hot water boilers, all pipes in the heating area are straight pipes. And there is enough cleaning hand hole device to facilitate manual and mechanical cleaning of dirt and internal inspection. The horizontal coal-fired atmospheric hot water boiler is equipped with a large manhole on the upper part, through which personnel can enter the furnace body. It greatly facilitates the inspection and maintenance of the boiler.
8.The boiler body has compact layout, small floor space, convenient transportation, quick-installation, short installation period, low installation cost, low user investment, and fast recovery.

9.Coal-fired hot water boilers/coal-fired heating boilers/coal-fired bathing boilers/coal-fired bath boilers are widely used in factories, hotels, hospitals, office buildings, schools, bathing centers, hotels, greenhouses, baths and other enterprises and institutions , To meet the bathing, domestic hot water and heating requirements of the user.
