Flame pressing type water tube boiler

Abstract

The invention discloses a flame pressing type water tube boiler in the field of steam generation devices, which comprises a vertically arranged boiler body, tubes are vertically arranged in the boiler body, the tubes are arranged in a concentric annular array, three layers of tubes are arranged from inside to outside, a flame pressing plate is arranged in a circular cavity formed by the tubes on the inner layer, and a hearth is arranged below the flame pressing plate; a spiral coil pipe is also arranged on the periphery of the tube array in the boiler body; and smoke baffles are arranged between the tubes on the adjacent layers and between the tubes on the outer layer and the spiral coil pipe respectively, flow separation components are arranged between the tubes on the same layer and on the inner sides or the outer sides of the tubes on the same layer, a vertically reciprocating baffling channel is formed between the flow separation components and the smoke baffles in the space in the hearth, and the outermost side of the baffling channel is connected to a smoke outlet. The flame pressing type water tube boiler is small in water storage amount and large in steam production amount. The flame pressing type water tube boiler can be made into fire coal, fuel oil, natural gas or biomass energy boilers and can be applied to various places needing steam.

Description

technical field [0001] The invention relates to a steam generating device, in particular to a water tube boiler. Background technique [0002] Boilers currently on the market mainly include water tube boilers and fire tube boilers; water tube boilers have furnace water in the tubes, and high-temperature flue gas generated by combustion in the combustion chamber is outside the tubes, forming a "fire-in-water" structure; fire tube boilers have relatively The large water bag, the combustion chamber and the high-temperature flue gas heat exchange mechanism are arranged in the water bag, forming a "water-in-fire" structure. Whether it is a water tube boiler or a fire tube boiler, there is a big problem at present that the volume of the boiler per unit steam output is relatively large, and the water storage in the furnace body is also relatively large. The water storage capacity in the body is usually more than 50 liters, and the economy is poor. [0003] In the Chinese patent d...

AI Technical Summary

Problems solved by technology

This device is actually a kind of boiler, and its shortcoming is that the volume of the furnace body of this device is not compact enough, and the volume of the boiler per unit steam output is still relatively large. Not efficient enough
