Double-output composite boiler

Abstract

A double-output composite boiler comprises a chamber and a flue, a conduction oil heat absorption device is arranged in the chamber, and a heat carrier heat absorption device is further arranged in the flue and comprises two heat carrier heat absorption convection sections which are connected in series. According to the double-output composite boiler, heat generated in the boiler is fully used to produce double output, the temperature of exhaust gas is reduced, the environment is protected, and energy is saved.

Description

technical field [0001] The invention relates to organic heat carrier boiler equipment, in particular to a double-output composite furnace. Background technique [0002] The organic heat carrier furnace started in the United States in the 1930s and was pioneered by the American Dow Biochemical Company. It is a new type of thermal energy equipment that uses coal, oil, and gas as fuel, and uses heat transfer oil as the circulating medium to provide heat. It uses a high-temperature circulating pump to force the heat transfer oil to perform closed-circuit circulation. After the heat is supplied to the heating equipment, it returns to the boiler for heating. , because the heating temperature can be precisely controlled, replacing the original steam boiler heating. [0003] Since the external heat is generally around 250°C or higher, the exhaust gas temperature of the organic heat carrier furnace is often higher than 300°C; for this part of the flue gas above 300°C, in addition to...

Problems solved by technology

However, the energy-saving recovery of smoke exhaust in the above scheme is not thorough, and the heat generated by the boiler cannot be fully utilized, which wastes energy.

[0006] Chinese patent CN102012096 discloses a gas-liquid two-phase organic heat carrier boiler, which heats the water supply system outside the boiler after heat-absorbing and vaporizing the heat-conducting oil. The boiler outputs both heated heat-conducting oil and heated hot water, basically achieving At the same time, it meets the needs of high-grade heat energy and low-grade heat energy, but it uses steam-state heat transfer oil to heat hot water, and heating the heat-conduction oil to steam state requires a high temperature, and due to its own structural limitations, it cannot improve heat conduction oil fuel utilization
