Energy-saving type steam-water universal boiler

Abstract

The invention provides an energy-saving steam-water universal boiler, which belongs to the technical field of boiler equipment and comprises a boiler barrel, an energy saver arranged below the boiler barrel, a condenser arranged below the energy saver and a smoke box arranged below the condenser. An eccentric furnace pipe is arranged in the boiler barrel, the axis of the eccentric furnace pipe deviates downwards relative to the axis of the boiler barrel, a burner connector is arranged at one end of the eccentric furnace pipe and extends out of the boiler barrel, and a smoke outlet is formed in the bottom end of the eccentric furnace pipe. The shell side of the energy saver is communicated with the smoke outlet and the shell side of the condenser, the shell side of the condenser is communicated with the smoke box, and a smoke outlet is formed in one side of the smoke box; by combining the characteristics of the hot water boiler and the steam boiler, the combination of the hot water boiler and the steam boiler is realized, the universality and replaceability of the product are improved, and meanwhile, the grading optimization arrangement of the energy saver and the condenser is realized through the optimization design of the boiler barrel, so that the improvement of the utilization rate of energy is facilitated.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to an energy-saving general-purpose steam-water boiler. Background technique [0002] A boiler is a mechanical device that uses the heat of fuel or other energy sources to heat water to generate steam or hot water. The boiler mainly includes the boiler and most of the furnace volume. And heating medium heating furnace, etc. [0003] Among them, a hot water boiler is a boiler that produces hot water, which refers to a thermal energy device that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to a rated temperature. The hot water produced by it is widely used. Used in heating equipment such as radiators and water heaters. [0004] A steam boiler refers to an industrial boiler that heats water to certain parameters and produces high-temperature steam. The water is heated in the drum to become s...

Problems solved by technology

[0005] At present, hot water boilers and steam boilers are mostly used alone, which is not easy to achieve versatility, resulting in an increase in product classification; in addition, no matter whether it is a hot water boiler or a steam boiler, the high-temperature flue gas generated during the combustion process cannot be fully utilized. Increased energy consumption to a certain extent, increased costs

[0006] In order to meet low-temperature discharge, pipes are generally used to connect condensers to cool down. The structure and arrangement are unreasonable, resulting in a large area occupied by the overall equipment and an increase in the amount of consumables. In addition, the heat of high-temperature flue gas can often take away the heat supply 20-50% of the heat of the flue gas. When recovering the waste heat of the flue gas, the heat carried by the flue gas is mainly converted into usable heat through a certain heat exchange method. Due to the connection of the pipes, it will cause a large loss of flue gas heat and affect the flue gas. Gas heat recovery rate
