Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings. The vertical porous medium furnace boiler of the present invention adopts the layout structure at the bottom of the burner to reduce the flow resistance of flue gas as much as possible. The burner continuously sends the low calorific value gas and the air for combustion support to the lower part of the furnace through the burner connection tube seat (2) and then enters the lower layer to position the porous medium body (8), the cylindrical porous medium body (9) and the shaped porous medium in sequence. The body (10) stores heat and burns, and then enters the upper layer to position the porous medium body (8). The pipe (12) enters the smoke box (11) after exchanging heat with the working medium water in the boiler, and discharges through the chimney (13).

[0018] The working medium water of the vertical porous medium furnace boiler of the present invention is sent to t...

Abstract

The invention discloses a vertical porous medium furnace boiler, which belongs to the technical field of energy saving and environmental protection, and comprises a burner connection pipe seat (2), a positioning porous medium body (8), a cylindrical porous medium body (9) and a shaped porous medium body ( 10), furnace shell (19) and pot shell (18). The low calorific value gas and air are mixed in the lower part of the furnace shell (19) through the burner connection socket (2) and then enter the lower layer to position the porous medium body (8), the cylindrical porous medium body (9) and the shaped porous medium body (10 ) after preheating and burning, burn out in the upper positioning porous medium body (8) and cylindrical porous medium body (9), and the generated flue gas enters the upper part of the furnace shell (19) and the smoke pipe (12). To the smoke box (11), and discharge through the chimney (13). The working medium water is sent into the boiler shell (18) through the water inlet pipe seat (5), and then is heated (heated and vaporized) by the furnace shell (19) and the smoke pipe (13), and then flows out of the boiler through the outlet water (steam) pipe seat (14). . The invention improves the ignition and combustion thermodynamic temperature of the low calorific value gas, promotes the burnout of the low calorific value gas, effectively solves the problem that the low calorific value gas is difficult to ignite and burn out, and saves energy.

Description

technical field [0001] The invention relates to a vertical porous medium furnace boiler, in particular to a boiler which can be used for full combustion and utilization of low calorific value gas. The boiler has a porous medium body capable of fully preheating and burning out in the furnace. Background technique [0002] Low calorific value gas is widely used in industrial production such as resource mining and processing. It has less combustible components and low calorific value. It is difficult to fully mix combustible components and oxidants during combustion, and it is difficult to ignite and burn out. In the actual production process, most of the low-quality gas is directly discharged. This not only causes environmental pollution, but also increases the waste of energy resources. [0003] Due to the high operating environment of industrial and civil boilers, most of them use oil and gas fueled fire tube boilers. The furnace is not only the combustion and heat release ...
