Casing tube boiler

Abstract

A sort of bushing boiler consists of the firebox, the water chamber, the outlet flue, the water inlet, the hot water, the stream outlet. It is located the heat transfer chamber above the firebox and the water chamber, it is located the hot smoke collection chamber and the hot hydrosphere chamber above the heat transfer chamber. It is set with the vertically bushing uniformly, the bushing consists of the inner canal and the outer canal. The firebox connects with the hot smoke collection chamber by the inner canal. The water chamber connects with the hot hydrosphere chamber by the clearance which is formed between the inner canal and the outlet canal. The center part of the heat transfer chamber is located the semi-open type center barrel, the smoke collection chamber connects with the smoke outlet by the semi-open type center barrel and the heat transfer chamber. The water of the stricture space of the boiler forms rapidly the superheated vapor or the hot water by many repeating calefaction. This invention can use the oil, gas, coal, biology to be the fuel, it has this excellence in that small bulk, a few water, big heat transfer area, high efficiency and it is heated soon, saved the fuel in this instance that it produces the same quantity of feat.

Description

technical field [0001] The invention relates to a heating equipment, in particular to a boiler for heating Background technique [0002] At present, there is no report on casing boilers. Most of the furnaces used in the market are central furnaces. The smoke pipes are arranged in the water chamber, and the flue gas returns to the lower part of the furnace body to be discharged. The disadvantages are that the furnace body is huge, the heat exchange area is small, the thermal efficiency is low, the water consumption is large, and the time for producing hot water or steam is long. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and propose a casing boiler with a small furnace body, a large heat exchange area, high heat exchange efficiency, fast hot water or steam output, and fuel saving. [0004] The purpose of the invention is achieved through the following technical solutions: [0005] The invention...
