Abstract
The utility model relates to a boiler system, including coal flashboard, economizer, be provided with the cooling water cavity in the coal flashboard, the cooling water cavity is equipped with water inlet and delivery port, and delivery port and economizer intercommunication through with coal flashboard and economizer intercommunication, can directly get into the economizer with fully having absorbed the thermal water of boiler oil in the coal flashboard to the glassware for drinking water that make to get into in the economizer has certain temperature, thereby further fuel economy improves boiler system's heat utilization rate, has also improved economic benefits simultaneously.
Description
Technical field
This utility model relates to field of boilers, particularly to a kind of steam generator system.
Background technology
On boiler, the structure of normally used coal flashboard is rectangular hollow box minor structure, refractory brick on building inside box, refractory brick one is facing to the burner hearth of boiler, but owing to the temperature in boiler furnace is significantly high, the refractory brick of coal flashboard will burn out after using a period of time, even partial melting, when the fire grate of gear boiler stops delivering coal forward, the flame of burner hearth directly burns on coal flashboard, and the at this moment damage of refractory brick will be more serious, thus causing the damage of coal flashboard structure. in prior art, by arranging water storage cavity in coal gate panel body, at coal flashboard two ends, cooling water outlet is set, realize coal flashboard is cooled by water circulation, such as publication No. is the CN104713114A day for announcing be 20150617 the disclosed a kind of water cooling boiler coal gate board of Chinese patent, including coal gate panel body, the water storage cavity of the hollow being arranged in described coal gate panel body, it is arranged on the cooling water inlet of described coal flashboard one end and is arranged on the coolant outlet of the described coal flashboard other end, dividing plate also it is disposed with up and down in the water storage cavity of the hollow in described coal flashboard, by recirculated water, coal flashboard is lowered the temperature. but, currently used water-cooled coal flashboard is in use, from coal flashboard coolant outlet out cooling glassware for drinking water have certain temperature, in order to make cooling effect better, typically require use recirculated water machine or cooling pond to circulating water, so making the heat energy in recirculated water not to be utilized effectively, recirculated water is cooled down by making time and cost of labor again, and steam generator system heat utilization rate is low, cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of steam generator system, with the low problem of steam generator system heat utilization rate of the prior art solved.
The technical solution of the utility model is: a kind of steam generator system, including coal flashboard, economizer, is provided with cooling water cavity in coal flashboard, and described cooling water cavity is provided with water inlet and outlet, and described outlet connects with economizer.
Arrange and the dividing plate of cooling water cavity wall composition bending water channel along water (flow) direction in the cooling water cavity of described coal flashboard.
Described dividing plate has at least two, and is divided into upper spacer and lower clapboard, and the bottom of upper spacer and the setting of lower clapboard interval and upper spacer is lower than the top of lower clapboard.
Described coal flashboard is provided with suspension ring.
Described water inlet is connected to intake pump.
The beneficial effects of the utility model are: described steam generator system, including coal flashboard, economizer, it is provided with cooling water cavity in coal flashboard, cooling water cavity is provided with water inlet and outlet, outlet connects with economizer, cooling water has certain temperature owing to having fully absorbed the heat of coal flashboard after the cooling water cavity of coal flashboard, by the outlet of coal flashboard is connected with economizer, can make to have the cooling water of uniform temperature enter economizer again with, save fuel further, improve the heat utilization rate of steam generator system, also improve economic benefit simultaneously, solve the problem that current steam generator system heat utilization rate is low.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the specific embodiment of a kind of steam generator system of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
The specific embodiment of a kind of steam generator system of the present utility model, as shown in Figure 1, described steam generator system includes coal flashboard 1, economizer 2, intake pump 3, cooling water cavity 11 it is provided with in coal flashboard 1, cooling water cavity 11 is provided with water inlet 12 and outlet 13, water inlet 12 is connected with intake pump 3 by high-temperature conduit, outlet 13 is connected with economizer 2 by high-temperature conduit, coal flashboard 1 is by being welded by Q245R steel plate, and cooling water cavity 11 internal welding is connected at least two dividing plate 14, dividing plate 14 arranges along water (flow) direction and coal flashboard outer wall vertical and forms bending water channel, the height of dividing plate has lap less than the height of coal flashboard inner chamber and adjacent two dividing plates in the projection in water (flow) direction, by in cooling water cavity 11 water routes arranging dividing plate 14 composition bending, the contact surface of coal flashboard 1 and cooling water can be increased, cooling water is made to fully absorb the heat on coal flashboard 1, cooling effect is better. being further fixed on suspension ring 15 on coal flashboard 1, coal flashboard 1 drives suspension ring about 15 adjustable by elevating mechanism.
When described steam generator system works, cooling water is squeezed into from water inlet 12 high pressure by intake pump 3 by high-temperature conduit, the temperature of coal flashboard 1 is reduced by the internal bending water channel being made up of dividing plate 14 of cooling water cavity 11, cooling water in cooling water cavity 11 is owing to the heat of absorption coal flashboard is with certain temperature, high-temperature conduit through outlet 13 enters economizer 2 and again makes full use of, thus saving fuel further, improving the heat utilization rate of steam generator system, also improving economic benefit simultaneously.
In other embodiments of the present utility model, described coal flashboard can also be without arranging dividing plate; Described dividing plate can also only arrange one; Described dividing plate can also be without and the outer wall vertical of coal flashboard.
