Abstract
A multi-fuel special-shaped hearth belongs to thermal technical field, wherein the utility model arranges a water jacket at periphery, the upper portion of the water jacket is embedded with a flue part of which is extruded outside the water jacket and provided with a smoke inlet facing the hearth, the furnace bed in the hearth is arranged with a flame guide barrel which upper is open, the wall of the flame guide barrel is arranged with a through hole which can be butted with the outlet of a combustion barrel of a burner, the bottom furnace bed of the hearth is arranged with an annular slope at periphery, while an air duct communicated with a fan is arranged under the furnace bed. When fuel is diesel or fuel gas, the furnace bed in the hearth is arranged with the flame guide barrel to mount the burner. When the fuel is coal and firewood, the flame guide barrel can be taken out and the burner is detached. The utility model can heat staple food and subsidiary food via one heating source, which can utilize diesel or fuel gas, coal or firewood. The hearth combines the structural characters of general kitchen range, shell boiler and waste-heat boiler, to resolve the technical problem that balances internal radiation receive face and convection receive face in various combustion conditions, which can save energy and improve efficiency.
Description
Technical field
The utility model belongs to the Thermal Equipment technical field, is specifically related to a kind of thermal efficiency height, energy-conserving and environment-protective, is suitable for the multi fuel furnace kitchen range burner hearth that fixing and vehicle-mounted cooking stove uses.
Background technology
The unit of having a dinner of group, as the open-air cooking kitchen range of office, school, hotel, dining car and army, the major and minor food cooking stove of most of employing independently is provided with heating source respectively and carries out food processing, and have following defective: energy utilization rate is low, and equipment volume is big; Cooking stove is only to use solid fuel or fluid fuel, bad adaptability.
The utility model content
The purpose of this utility model is to solve the deficiency that existing cooking stove exists, provide a kind of many fuel special-shaped burner hearth, realize adopting a heating source can carry out major and minor food processing simultaneously, and both can use with diesel oil or combustion gas burner and heat as fuel, take off behind the burner again can coal or bavin be fuel.
Structure of the present utility model: outer periphery water jacket, water jacket is provided with steam (vapor) outlet, water jacket is embedded with flue in the top, flue some to stretch out water jacket outer and have a gas approach in burner hearth, inner of the boiler chamber row goes up and places the uncovered down-draft cylinder in a top, offer a through hole that can dock with the combustion barrel outlet of burner on the down-draft cylinder wall, fire grate outer periphery one annular is domatic at the bottom of the burner hearth, and the fire grate below is the air duct that is communicated with blower fan.
The of the present utility model use and operation principle: fuel is during as diesel oil or combustion gas, inner of the boiler chamber row goes up and places down-draft cylinder, install burner, allow the combustion barrel outlet of burner dock with the through hole of down-draft cylinder wall, the flame and the high-temperature flue gas of combustion barrel ejection upwards flow under the effect of down-draft cylinder inwall, make flame and flue gas can be close to the bottom of a pan the bottom of a pan is evenly heated.Water in the heat heating furnace water jacket that burner hearth absorbs makes water generates steam processing staple food.Last flame is converted into high-temperature flue gas, and the gas approach of high-temperature flue gas by flue enters the flue that is embedded in the hearth water sleeve, the water among the heating water jacket once more, and flows along flue, drains into atmosphere.Waste heat in the flue gas is utilized once more, greatly reduces the chimney emission temperature.When using coal, bavin, in burner hearth, take out down-draft cylinder, get final product behind the burner of dismantling.Frame is placed on the coal on the fire grate, and because of the annular domatic flame root temperature that improved of fire grate periphery at the bottom of the burner hearth, the wind that blower fan produces carries out combustion-supporting to coal by the wind bucket, guaranteed stable ignition and the furnace high-temperature of coal under low load condition, realizes overheavy firing.
The beneficial effects of the utility model: adopt a heating source can carry out the processing of major and minor food simultaneously, and both can use with diesel oil or combustion gas burner and heat as fuel, take off behind the burner again can coal or bavin be fuel.The burner hearth of this special construction organically blends the design feature of common cooking kitchen range and smaller hard flour pancake boiler, waste heat boiler, and burner hearth is provided with water jacket and has strengthened heating surface area.Flame can evenly flow in burner hearth, solved the technical barrier that uses under the pluralities of fuel condition radiation heating-surface and convection heating surface in the stove to take into account layout, but the heat energy stage construction absorbs energy efficiency.
Description of drawings
Master when Fig. 1 uses oil or combustion gas for embodiment looks cross-sectional view.
Master when Fig. 2 uses fire coal for embodiment looks cross-sectional view.
The specific embodiment
See the embodiment of Fig. 1, Fig. 2.Establish water jacket 3 between inboard wall of burner hearth 1 and the hearth outer wall 2.4 is burner 4.Water jacket is embedded with flue 5 in 3 tops, flue 5 some to stretch out water jacket 3 outer and have a gas approach 6 in burner hearth.Place the uncovered down-draft cylinder 8 in a top on the inner of the boiler chamber row 7, offer a through hole that can dock on down-draft cylinder 8 walls with the combustion barrel outlet of burner 4.Fire grate 7 outer periphery one annular domatic 9 at the bottom of the burner hearth.Fire grate below be the air duct 10,11 that is communicated with blower fan for connecing ash bin, 12 and 13 expression flames, and 14 is fire door, and 15 represent fire coal, and 16 is the refractory masses that is layed in down-draft cylinder 8 bottoms.
Above embodiment only is described further the utility model, and scope of the present utility model is not subjected to the limitation of illustrated embodiment.
Claims (2)
1. the special-shaped burner hearth of fuel more than one kind, it is characterized in that: the outer periphery water jacket, water jacket is provided with steam (vapor) outlet, water jacket is embedded with flue in the top, flue some to stretch out water jacket outer and have gas approach in burner hearth, inner of the boiler chamber row goes up and places the uncovered down-draft cylinder in a top, offers a through hole that can dock with the combustion barrel outlet of burner on the down-draft cylinder wall, fire grate outer periphery one annular is domatic at the bottom of the burner hearth, and the fire grate below is the air duct that is communicated with blower fan.
