Description

A kind of steam combustion-supportinboiler boiler
Technical field
The present invention relates to a kind of boiler, particularly relate to a kind of steam combustion-supportinboiler boiler.
Background technology
Existing steam combustion-supportinboiler boiler a kind ofly can carry out combustion-supporting boiler to burner hearth fuel injection water steam, this boiler is provided with water cavity and burner hearth, water in boiler water cavity after heating enters outside radiator, enter boiler water cavity again by the cooled water of radiator to heat, water in such water cavity is just constantly recycled heating and heat radiation, burner hearth is provided with steam generator, is equipped with water tank outside boiler, and water tank provides water source for steam generator.Described steam generator comprises heating tube, steamdrum and steam jet, heating tube is connected with steamdrum, steamdrum is connected with the inner chamber water surface superjacent air space of water tank, steamdrum is connected with steam jet, and heating tube is distributed in burner hearth, and steam jet is positioned at burner hearth bottom, heating tube is connected with water tank and is provided with inlet valve, when stove fire burning is more prosperous, at this moment need manual operation inlet valve, the water entering heating tube is reduced; When stove fire burning is not prosperous, at this moment needs manual operation inlet valve, the water entering heating tube is increased gradually.Therefore, this existing structure steam combustion-supportinboiler boiler needs special messenger and carries out real-time operation according to stove fire combustion case, wastes time and energy, uses inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of easy to use, do not need the steam combustion-supportinboiler boiler that special messenger operates.
Technical solution of the present invention is: a kind of steam combustion-supportinboiler boiler, comprise boiler and pressure balance valve, boiler is provided with water cavity and burner hearth, be equipped with water tank outside boiler, burner hearth is provided with steam generator, and described steam generator comprises heating tube, steamdrum and steam jet, heating tube is connected with steamdrum, steamdrum is connected with the inner chamber water surface superjacent air space of water tank, and steamdrum is connected with steam jet, and heating tube is connected with water tank, described pressure balance valve comprises valve body, spool, valve inner is provided with body cavity, valve body left end is provided with vapor interface, valve body right-hand member is provided with hickey, body cavity and vapor interface, hickey communicates, vapor interface communicates with the inner chamber water surface superjacent air space of water tank, body cavity is provided with spool, valve body is provided with water inlet and delivery port, water inlet and delivery port are corresponding up and down and communicate with body cavity, spool is the axle that centre is provided with annular groove, the outer wall at spool two ends and the inwall of body cavity suitable, hickey is equipped with pressure adjusting bolt, between pressure adjusting bolt and spool, pressure spring is housed, when spool moves to pressure spring direction, the annular groove be provided with in the middle of spool is between water inlet and delivery port and water inlet and delivery port are communicated, when spool moves to vapor interface direction, water inlet and delivery port cut off by the outer wall of spool right-hand member, run through at the inner chamber water surface superjacent air space of water tank and have cooling water pipe, the water inlet end of cooling water pipe is communicated with the lower end of water cavity by the delivery port of pressure balance valve and water inlet, and the water side of cooling water pipe communicates with the upper end of water cavity.
Above-mentioned cooling water pipe is the high slant setting in the low water side of water inlet end.
The outer wall of above-mentioned cooling water pipe is provided with fin.
Technique effect of the present invention is: the present invention increases pressure balance valve on the basis of existing steam combustion-supportinboiler boiler, body cavity is provided with spool, spool one end is provided with pressure spring and pressure adjusting bolt, the spool other end communicates with the water surface superjacent air space of water tank, when stove fire burning is more prosperous, at this moment the steam pressure in steamdrum increases, because steamdrum of the present invention communicates with the inner chamber water surface superjacent air space of water tank, the water surface superjacent air space of water tank communicates with the vapor interface of pressure balance valve again, the steam of larger like this pressure will promote spool and moves to the right and compress pressure spring, when annular groove in the middle part of spool moves to spool and water inlet and delivery port to the time in of corresponding at this moment water inlet and delivery port are communicated by spool intermediate annular groove, because the water of boiler water cavity lower end heating flows to boiler water cavity upper end, therefore, the water of boiler water cavity lower end will be flowed to the upper end of boiler water cavity by pressure balance valve water inlet and delivery port.Again because the water temperature in boiler water cavity is less than the temperature of water tank cavity water surface superjacent air space water vapour, thus flow through the water vapour of the water cooling water tank cavity water surface superjacent air space of cooling water pipe, the temperature of water tank cavity water surface superjacent air space water vapour is reduced, thus the pressure of water tank cavity water surface superjacent air space water vapour is reduced, and then the pressure of the water vapour in steamdrum is reduced, reduce the steam discharge rate of steam jet, alleviate fuel and cross prosperous burning.When burner hearth fuel combustion is not prosperous, the pressure of the water vapour in steamdrum reduces, spool is under the reset response of compression pressure spring, spool is moved to the left, when the passage of spool right-hand member closed front water inlet and delivery port, at this moment the water of the top and bottom of boiler water cavity is cut off, water stops flowing, the water no longer cooling steam of cooling water pipe, the temperature of water tank cavity water surface superjacent air space water vapour is increased gradually, thus the pressure of water tank cavity water surface superjacent air space water vapour is increased gradually, and then the pressure of the water vapour in steamdrum is improved, thus improve the steam discharge rate of steam jet, fuel is made to cross prosperous burning.Like this, when the adjustment of pressure adjusting bolt is in constant position, spool is under the acting in conjunction of steam pressure and pressure spring, steam pressure keeps a constant pressure, boiler oil is burnt and keeps stable state, thus replaces special messenger's operation, time saving and energy saving, easy to use, and novel structure is practical.
