Abstract

A kind of briquet for chafing dish.The invention belongs to a kind of domestic fuel, it is made up of coal, plain carbon, industrial waste, wood charcoal powder, additive and binding agent, through stirring, rolling, be molded into the oblate spheroid shape coal briquette that diameter is 38 millimeters of Φ, it is ignited conveniently, available match direct ignition, and is easy to manufacture, cost is low, firepower is big, and combustion time is long, and is easy to use, health can be saved a large amount of timber simultaneously.

Description

Briquet for chafing dish

The invention belongs to a kind of domestic fuel.

Coal and charcoal have a long history as civilian fuel.Domestic life fuel mainly contains honeycomb briquette, goes up honeycomb briquet lighting, handwarmer coal briquette and charcoal etc. at present.Along with improving constantly of people's living standard, chafing dish generally enters family, hotel and restaurant as a kind of tableware of indispensability.And go up honeycomb briquet lighting is to do the raw material of igniting with paraffin or rosin, its complete processing complexity, and processing parameter requires high, expensive raw material price, and cigarette is many during burning, and supporting stove and accessory requires high, is not suitable for doing fuel for chafing dish.The handwarmer coal briquette is the oxidation formulation, and the cost of material height is lighted the no flare in back, provides heat with the form of oxidizing fire, and its heat is little, can not be as the fuel of chafing dish.The fuel of chafing dish all adopts charcoal at present.Use charcoal to make fuel for chafing dish, its cost height, ashes food of easily making dirty influence health, simultaneously a large amount of timber of needs when firing charcoal.

The purpose of this invention is to provide a kind of is the briquet for chafing dish of main raw material with the coal.This briquet for chafing dish is the naked light burning, available match direct ignition.

The said briquet for chafing dish of the present invention, its raw material consists of:

1, coal class; Can adopt hard coal, long-flame coal, brown coal etc.

2, plain carbon class; Can adopt wood sawdust, bagasse, husk, shell, branch, leaf etc.

3, industrial waste class; As flue dust, flyash, emery wheel ash etc.

4, wood charcoal powder or ash;

5, bonding starch based; As Semen Maydis powder, sweet potato powder, mealy potato etc.

6, additive kind; In sodium bicarbonate, sodium hydroxide, calcium superphosphate, SODIUMNITRATE, ammonium nitrate, the nitrate of baryta several mix.

The weight percent of above-mentioned various raw materials is:

1, coal 30-70%; 2, plain carbon 5%-35%

3, industrial waste 5%-10%; 4, wood charcoal powder 0-30%

5, binding agent (adding) 10-25%; 6, additive 5%-35%

Wherein the weight percent of each constitutive material in the additive is:

Sodium bicarbonate: 0.1%-10%; Sodium hydroxide: 0.5%-3%

Calcium superphosphate: 0.5%-8% SODIUMNITRATE: 3%-15%

Ammonium nitrate: 1%-10%; Nitrate of baryta: 5%-20%

Briquet for chafing dish of the present invention can divide two big classes according to the difference of main raw material: a class arrives less than 30% for adding ash wood; Another kind of for not adding wood charcoal powder.Form and degree is made into compound according to above-mentioned raw materials, outer adding additives after stirring, rolling, moulding oven dry, get final product finished product.

Briquet for chafing dish of the present invention have ignites fast, easy to manufacture, cost is low, can light a fire with match, and combustion time is long, firepower is big, meets hygienic requirements, can reduce the consumption of charcoal simultaneously, for country saves a large amount of timber.

Embodiment:

Raw materials such as coal, plain carbon raw material, industrial waste, charcoal are ground into the powder of granularity＜1mm with pulverizer, additive is ground into＜powder of 0.1mm, preparing burden into gross weight by following prescription is 150 grams

Coal: 45%; Wood charcoal powder: 20%; Plain carbon raw material 10%;

Additive: 25%;

Consisting of of additive wherein:

Sodium bicarbonate: 2% sodium hydroxide: 1%;

Calcium superphosphate: 3%; SODIUMNITRATE: 5%

Nitrate of baryta: 14%.

Above-mentioned raw materials is mixed, add small amount of binder, stir, rolling, moulding, oven dry, can obtain diameter is the oblate spheroid shape briquet for chafing dish of φ 38mm.

Claims

1, a kind of briquet for chafing dish is characterized in that whole coal briquette is made up of coal, plain carbon, industrial waste, wood charcoal powder, binding agent and additive, and the weight percent of each raw material is:

Coal 30%-50%, plain carbon 5%-35%, industrial waste 5%-10%, wood charcoal powder 0-30%, binding agent (adding) 10-25%, additive 5%-35%.

2, according to claim 1 described briquet for chafing dish, it is characterized in that additive is made up of sodium bicarbonate, sodium hydroxide, calcium superphosphate, SODIUMNITRATE, ammonium nitrate, nitrate of baryta, its weight percent is sodium bicarbonate 0.1%-10%, sodium hydroxide 0.5%-3%, calcium superphosphate 0.5%-8%, SODIUMNITRATE 3%-15%, ammonium nitrate 1%-10%, nitrate of baryta 5%-20%, gross weight is no more than 35%.
