Casthouse shaped coal forming machine for industrial boiler

Abstract

The invention discloses a furnace front coal forming machine used for a industrial boilers, which comprises a coal scuttle, an additive inlet, an additive brush, coal equalizing rollers, forming rollers, a coal poking cylinder, a sieve bend, a partition, a coal gate. Both the forming rollers and the coal equalizing rollers are pairs of rollers; each pair of rollers consists of a driving roller and a driven roller. The driven roller is provided with a return spring. The forming rollers are driven by the chain grates of the industrial boiler. The outside diameters of the forming rollers are provided with ball-and-socket type moulds, which are arranged in a staggered way. The ball-and-socket type moulds are oval with protrudent S-shaped lug bosses on the central lines. Combining the stratified combustion technology with the cold state pressure moulding technology, the invention is an upper screening and lower moulding coal supply device, and is applicable for various chain industrial boilers. The invention is also applicable for other types of stratified combustion industrial boilers by slightly changing the screening device of the invention. Boilers adopting the furnace front coal forming machine can effectively improve the burn-off rate of the fuel, and greatly reduces q4 with the coal saving ratio improved by more than 15 percent. Users need only a little investing on the invention, but can get high economical efficiency of operation.

Description

technical field [0001] The invention belongs to the technical field of thermal energy engineering application, and in particular relates to a furnace-front briquette forming machine for industrial boilers. Background technique [0002] China is a country where coal is the main energy source. Coal accounts for 75% of the energy composition, and 85% of China's total coal output is directly burned. The scattered burning of coal not only wastes energy, but also causes extremely serious environmental pollution. Today, our country is striving to build an energy-saving and environment-friendly society. Therefore, it has become an urgent task to make coal burn cleanly. [0003] There are more than 520,000 industrial boilers in the country, of which more than 80% are layer-fired combustion methods, and 70% are chain boilers, and their coal consumption accounts for more than 25% of the national coal consumption. therefore. Solving the coal combustion proble...

Problems solved by technology

This type of forming die has the advantages of simple structure and convenient processing; at the same time, there are many shortcomings, the most prominent problem is that during installation and operation, the ball and socket molds of the driving roller and the driven roller need to be centered. , once the ball and socket mold is eccentric, the molding rate will drop significantly, and in severe cases, the molding machine will not be able to shape
