Problems solved by technology

Boilers with such a structural principle have two disadvantages: 1. Because low-temperature water enters the boiler combustion chamber, it will reduce the temperature of the combustion chamber, which is not conducive to the full combustion of fuel and affects the release of heat.
2. The water that has obtained the temperature is heated by the low-temperature flue gas. Because the temperature difference between the two is small and the heat exchange rate is low, a large part of the heat cannot be absorbed by the water, and is discharged to the atmosphere with the flue gas.
The current boilers have high exhaust gas temperature and low heat utilization rate, and the actual thermal efficiency of industrial hot water boiler heat is below 75%.

Embodiment Construction

[0013] When installing and using the drum preheating hot water boiler, connect the water inlet 8 in the upper drum area with the user's return water pipe, and connect the water outlet 9 in the lower drum area with the user's water outlet.

[0014] When the boiler is working, the low-temperature water passes through the water inlet 8 of the upper drum area and the upper drum area 6, and has sufficient heat exchange with the low-temperature flue gas of the smoke pipe 3; The heat absorber water inlet 10 of the combustion chamber enters the heat absorber 2 of the combustion chamber for high-temperature heating, and the water with elevated temperature passes through the lower drum area 5 and is discharged to the user through the lower drum area water outlet 9 .

Abstract

A hot water boiler of preheated boiler cylinder is prepared as setting boiler cylinder with flue and heat absorber in combustion chamber independently and relatively, setting water outlet and inlet at top and bottom of boiler cylinder and setting water outlet and inlet at top and bottom of heat absorber in combustion chamber then connecting water outlet of boiler cylinder to water inlet of heat absorber in combustion chamber.

Description

technical field [0001] The invention relates to the technical field of industrial hot water boilers, in particular to an industrial water and fire tube hot water boiler with a smoke tube drum. Background technique [0002] There are various structures of industrial hot water boilers on the market, but there is a common principle: low-temperature water first enters the boiler combustion chamber directly or indirectly to be heated at high temperature, and the water that has obtained the temperature is then heated by the low-temperature flue gas from the boiler flue pipe. Boilers with such a structural principle have two disadvantages: 1. Because low-temperature water enters the boiler combustion chamber, it will reduce the temperature of the combustion chamber, which is not conducive to the full combustion of fuel and affects the release of heat. 2. The heated water is heated by the low-temperature flue gas. Since the temperature difference between the two is small and the hea...
