Abstract

The utility model relates to highly effective normal pressure heat pipe type molded coal boiler which is composed of a boiler casing, flues positioned in the boiler casing, and a fire grate in a boiler chamber, wherein eight flues are arranged in the boiler casing, and are divided into two layers; smoke dust is exhausted by an upper and a lower layers of flues in an 's ' shape; vertical type heat pipes which are uniform distributed along the length direction of the flues are arranged among the flues; the lower ends of the heat pipes penetrate through the boiler chamber to enter a combustion chamber so as to heat water, and the heat pipes are communicated with a water jacket of the boiler casing. The utility model can achieve the smoke gas emission standards of national class A areas without a blower fan, a draught fan and desulphurizing and dust-removing equipment, simultaneously has the heat efficiency which reaches more than 83%, simultaneously has the advantages of simple and reliable operation, time saving, labor saving, easy installation and easy scale removal, and is an ideal environmental protection boiler for both urban and rural areas.

Description

Efficient normal pressure heat pipe-type molded coal boiler

Technical field: the utility model relates to a kind of boiler, particularly a kind of normal pressure heat pipe-type molded coal boiler.

Background technology: the diffusing coal of the general burning of fixed grate normal-pressure hot-water boiler in the market, layer coal, because furnace binding reason, it is insufficient to burn, the one, the thermal efficiency is low, the 2nd, severe contamination atmospheric environment, for making flue gas reach discharge standard, just needing increases desulfurization, cleaner, has increased the cost of boiler operatiopn.

Goal of the invention: for addressing the above problem, the utility model provides a kind of efficient normal pressure heat pipe-type molded coal boiler, does not need to increase desulfurization, cleaner, only needs gravity-flow ventilation, and smoke emissioning concentration can be lower than 80mg/Nm ³, the Lin Keman blackness is turned a blind eye to, and is better than national class area discharge standard greatly; The thermal efficiency can reach more than 83% simultaneously.

Technical scheme: boiler is made up of furnace shell, flue, flue gas retained chamber, water heating cabinet, flue and heat pipe, and furnace shell has water leg, owing to preheating water, can significantly reduce the thermal loss of body of heater, makes full use of the energy; Furnace shell is provided with water inlet pipe, outlet pipe, evacuated tube and outlet flue; Fire grate is arranged in flue, the front end of fire grate has the moulded coal propeller, have in the water heating cabinet of flue top and be divided into bilevel eight flues and pass, one end of following one deck flue communicates with boiler furnace, for advancing mouth, the left end of the other end and last layer flue all is opened on flue gas retained chamber, the right-hand member of upper strata flue communicates with the boiler outlet flue, be that flue dust is serpentine through up and down two-layer flue discharging, making flue dust be able to abundant dirt falls, and the heat of flue dust is fully utilized, reduces heat waste, improve the thermal efficiency; The vertical heat pipe of evenly arranging along the flue length direction is arranged between the flue in the water heating cabinet, and its lower end is passed flue and is entered the combustion chamber, and upper end open is carried out the heating to water in the water heating cabinet, and the water heating cabinet is communicated with by communicating pipe with boiler furnace shell chuck.

Beneficial effect: owing to adopt technique scheme, the utlity model has need not air blast, air-introduced machine and desulfurization, cleaner, only needs gravity-flow ventilation, can reach smoke emissioning concentration and be lower than 80mg/Nm ³, the Lin Keman blackness is turned a blind eye to, and is better than national class area discharge standard greatly; The thermal efficiency can reach more than 83% simultaneously.Operation is simple and reliable simultaneously, time and labour saving, easy for installation, and scale removal is easy, is desirable town and country environment-protection boiler.

Description of drawings: Fig. 1 is a front view of the present utility model;

Fig. 2 is a left view of the present utility model.

Embodiment: as shown in Figure 1, boiler is made up of furnace shell 1, flue 12, flue gas retained chamber 7, water heating cabinet 13, flue 4 and heat pipe 8, and furnace shell 1 is a water leg, owing to preheating water, can significantly reduce the thermal loss of body of heater, makes full use of the energy; Furnace shell 1 is provided with water inlet pipe 14, outlet pipe 11, evacuated tube 10 and outlet flue 5, fire grate 2 is arranged in flue 12, and the front end of fire grate 2 has moulded coal propeller 3, has eight flues 4 to pass in the flue 12 top water heating cabinets 13, these eight flues are divided into two-layer up and down, four every layer; One end of following one deck flue 4 communicates with boiler furnace 9, for advancing mouth 6, the left end of the other end and last layer flue all is opened on flue gas retained chamber 7, the right-hand member of upper strata flue communicates with boiler outlet flue 5, be that flue dust is serpentine through up and down two-layer flue discharging, make flue dust when being able to abundant dirt and falling, its heat also is fully utilized, reduce heat waste, improve the thermal efficiency; The vertical heat pipe 8 of evenly arranging along the flue length direction is arranged between flue 4, and its lower end is passed flue 12 and is entered combustion chamber 9, and upper end open is carried out the heating to water in water heating cabinet 13, and water heating cabinet 13 is communicated with by communicating pipe 15 with boiler furnace shell chuck.

Claims
