Abstract
A coal economizer for a boiler comprises a shell. The upper end of the shell is connected with a gas inlet channel, and the lower end of the shell is connected with a gas outlet channel. The coal economizer is characterized in that a serpentine tube is arranged in the shell, and a water inlet and a water outlet of the serpentine tube are respectively arranged on the outer side of the shell. The coal economizer has the advantages that 1, the coal economizer can realize preheating by the aid of tail gas generated during burning of the boiler, is favorable for reducing energy loss and saving energy, and reduces production cost, 2, the coal economizer is simple in structure and convenient in processing and manufacturing, and 3, the coal economizer reduces high-temperature tail gas discharge, is favorable for purification, and prevents air pollution.
Description
[technical field]
The utility model relates to a kind of boiler technology field, relates to a kind of economizer that is used for boiler in particular.
[background technology]
At present, burning boiler generally all is to adopt COAL-WATER SLURRY TECHNOLOGY, and coal will be as reliable, the most most economical energy sources of China in considerable time.Substitute fuel oil with COAL-WATER SLURRY TECHNOLOGY, not only can save cost, also help Industry Promotion and use.
Yet when using the water-coal-slurry burning boiler, water-coal-slurry can produce a large amount of high-temperature tail gas, and the discharging of high-temperature tail gas not only causes environmental pollution, also causes a large amount of wastes of energy.Therefore, the utility model is designed a economizer at the deficiencies in the prior art.
[utility model content]
The purpose of this utility model provides a kind of tail gas that produces when burning coal that utilizes water is preheated, and helps the economizer that is used for boiler of energy savings.
The purpose of this utility model is achieved in that
A kind of economizer that is used for boiler, the upper end that includes housing, housing is connected with inlet channel, the lower end of housing is connected with outlet passageway, it is characterized in that being provided with in housing coiled pipe, and the water inlet of described coiled pipe and delivery port are separately positioned on the outside of housing.
Aforesaid a kind of economizer that is used for boiler is characterized in that described coiled pipe is provided with many rows, and every row's coiled pipe is connected to end.
Aforesaid a kind of economizer that is used for boiler is characterized in that described coiled pipe is horizontally-arranged and vertical setting of types is crisscross arranged.
The beneficial effects of the utility model have: the tail gas that produces when 1, economizer can utilize burning boiler preheats, and helps reducing energy loss, helps energy savings, reduces production costs; 2, simple in structure, be convenient to processing and manufacturing; 3, reduce the exhaust emissions of high temperature, helped purifying, prevented air pollution.
[description of drawings]
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the utility model schematic diagram one;
Fig. 2 is the utility model schematic diagram two.
[specific embodiment]
As shown in the figure, a kind of economizer that is used for boiler of the utility model indication, the upper end that includes housing 1, housing 1 is connected with inlet channel 2, the lower end of housing 1 is connected with outlet passageway 3, wherein be provided with coiled pipe 4 in housing 1, the water inlet 5 of described coiled pipe 4 and delivery port 6 are separately positioned on the outside of housing 1.
In the middle of the utility model, described coiled pipe 4 can be arranged to many rows, and every row's coiled pipe 4 is connected to end.Described coiled pipe 4 can also be horizontally-arranged and vertical setting of types is crisscross arranged.
The utility model is using leaf, described soft water is in water inlet 5 enters coiled pipe 4, because the tail gas that burning boiler produced enters in the housing 1 from inlet channel 2, with coiled pipe 4 row heat exchanges, after the soft water in the coiled pipe 4 is heated, pump in the boiler by delivery port 6 again, by tail gas soft water is preheated, reduced energy loss, improved the efficiency of heating surface, helped reducing production costs.Heating tail gas later then enters in the atmosphere through after the purified treatment, avoids the pollution to air.
