Energy-saving low-discharge heating boiler

Abstract

This invention provides low energy consumption, low discharge heat supply boiler; it relates to a civil boiler that is hot water heating field. It includes up center header tank (boiler barrel), down header tank, water screen tube bundle, three return pipe rack, lateral up and down header tank (boiler barrel) and convection bank of tubes. Water screen tube bundle is connected to up center header tank and down header tank. Furnace radiation heating surface, three return flues and convection heating surface is consisted by consisted by front, back and lateral walls and furnace ceiling and three return ceiling. Two return flues or convection heating surface is consisted by convection bank of tubes connecting to up and down header tanks. Full compulsive cycle or half compulsive half natural cycle water route is consisted by setting separator, communicating tube equipment and down cast. Its technique is advanced, structure is compact, low steel consumption, low electricity consumption and low discharging and other composite benefit is very great by three space enlargement and natural economic flow speed in furnace. Its technique feature can be widely used in civil boiler.

Description

technical field [0001] The invention relates to the field of a civil boiler, that is, a hot water boiler. Background technique [0002] There are many types of heating boilers currently on the market, but they can be classified into two categories: one is water-fire tube boilers; the other is water-tube boilers. The common disadvantages of these two types of boilers are high steel consumption, high concentration of boiler smoke and dust, high smoke and wind resistance, and high power consumption. The different disadvantages of these two types of boilers are that the water-fire tube boilers have many tube plate cracks and tube bursts, and the failure rate is high. The process of water tube boilers is complicated, the production efficiency is low, and the cost is high. For this reason, the invention solves these shortcomings existing in current boilers, and is an ideal heating boiler with low energy consumption and low emissions. Contents of the invention [0003] The inve...
