30-liter constant-pressure steam boiler

Abstract

The invention discloses a 30-liter constant-pressure steam boiler. The smoke discharging tube of the 30-liter constant-pressure steam boiler is arranged on the other side surface above a coaling port between a hearth and a furnace pipe; the length of the smoke discharging tube is 60-100cm, and the upper end of the smoke discharging tube is slightly higher than the top of the furnace pipe; a superconductive heat transfer tube is arranged between the hearth and the furnace pipe; the lower end of the superconductive heat transfer tube is lower than the lowest point of a chimney opening; the hearth is a taper-shaped cavity of which the depth is 40-60cm and the diameter is 30-60cm, the top of the taper-shaped cavity is narrow, and the bottom of the taper-shaped cavity is wide; a furnace holder interlayer water jacket is arranged among a furnace holder, the hearth and a coal ash discharging cavity; a furnace pipe interlayer water jacket communicated with the furnace pipe is arranged between the furnace pipe and a shell; the two interlayer water jackets are mutually communicated; and a water inlet tube is arranged below the interlayer water jacket between the furnace holder and an ash outlet.

Description

technical field [0001] The invention relates to a 30-liter atmospheric pressure steam boiler. Background technique [0002] Most of the existing coal-fired steam boilers are large-scale boilers with large volume and pressure exceeding normal pressure; such boilers can only be used after being monitored and certified by the national monitoring department every year; and atmospheric pressure steam boilers with a pressure of 30 liters within one kilogram should not be used. It can be used after the national monitoring part of the monitoring and identification, and is very popular in the market. The existing 30-liter atmospheric pressure steam boiler usually includes a furnace base, an ash outlet below the furnace base, a furnace, a furnace installed above the furnace, and a chimney installed in the middle of the furnace. Insufficient coal; a blower is required for use, and the cost is high; (2) The smoke exhaust pipe is installed in the middle of the boiler directly above the ...

Problems solved by technology

The existing 30-liter atmospheric pressure steam boiler usually includes a furnace base, an ash outlet below the furnace base, a furnace, a furnace installed above the furnace, and a chimney installed in the middle of the furnace. Insufficient coal; a blower is required for use, and the cost is high; (2) The smoke exhaust pipe is installed in the middle of the boiler directly above the furnace, and its smoke pipe is long. On the one hand, the smoke pipe occupies the volume of the furnace , so that the amount of hot water and steam is reduced; in addition, due to insufficient combustion, a certain amount of heat energy is carried away, and a large amount of solid dust in the smoke is still discharged into the air, which pollutes the environment; (3) Insufficient combustion of fuel releases The thermal energy of the furnace is not fully utilized, and there is no water jacket outside the furnace, or it is only installed on the outer periphery of the furnace, but there is no water jacket on the outer periphery of the furnace base and the outer side of the coal ash chamber, and the thermal efficiency is low.
