Brick hearth type steam boiler

Abstract

The invention discloses a brick hearth type steam boiler. The steam boiler consists of a steam boiler (1), refractory bricks (2), an ash removal port (3), a counter-burning path (4), a fire grate (5), an underground ash pit (6), a ground plane (7), an ash removal cover (8), a brick counter-burning hearth (9), a brick hearth (10), a smoke receiving tube port (11) and a brick acid aluminum plate (12), wherein the hearth of the steam boiler can be completely built by using the refractory bricks or can be built by combining the refractory bricks and normal bricks; the brick acid aluminum plate (12) is sandwiched in the middle of the two types of bricks and is used for preserving and insulating heat; the biomass boiler (1) is arranged on the hearth; and the underground ash pit (6) is arranged below the ground plane (7). The steam boiler is easy to prepare, overhaul and popularize, has long life, is low in manufacturing cost, and is economical and practical.

Description

technical field [0001] The invention belongs to a steam boiler, in particular to a brick furnace type steam boiler. Background technique [0002] Taking advantage of the high temperature of steam, steam boilers are generally used in industry to maintain products, process heating, or also for heating. Our general steam boiler furnace is all welded with iron, so its cost is relatively high, and the fuel combustion temperature is high, the furnace is easy to deform, burn down, leak water after burning down, and is not easy to repair. Contents of the invention [0003] The present invention provides a brick-laying hearth type steam boiler aiming at the problems of the above products, which solves the problems of high cost, easy deformation of the furnace, collapse of the furnace, water leakage after collapse, and difficulty in maintenance. [0004] The present invention adopts the following technical scheme, a brick-laying furnace type steam boiler, comprising a steam boiler ...
