Description
Technical field
The utility model belongs to Forge Heating technical field, particularly a kind of gas-fired heater burner flame monitoring system.
Background technology
When natural gas heating furnace fuel burner nozzle (hereinafter referred to as fuel burner nozzle) works, flame monitoring (hereinafter referred to as fire prison) is divided into two kinds, and one is ionization type, and another kind is ultraviolet type.Effect, the effect of two kinds are identical, but its version and the difference such as service life and operation principle.Ionization type be work in burner hearth, by the fabrication hole on burner by electric power bar insert burner hearth, enter the direct perception burner flame in burner combustion district; Ultraviolet type be work outward at burner hearth, by burner fabrication hole monitoring burner combustion flame.These two kinds of modes are all by call wire metering-in control system, but these two kinds fire prisons are not identical with the interface mode of holding wire, and what ionization fire prison adopted is M14x1.25 fine thread interface, and what the inspection of ultraviolet fire adopted is
12mm close nipple.In addition, say from itself, ionization fire inspection structure is simple, price is low, monitoring range is narrow, fuel burner nozzle long-term work under about 1300 DEG C, thermal-flame radiation, oxidation cause burner hydraulic performance decline, flame slightly slight deformation time, ionization type fire prison just monitoring, less than the flame (reason detection range is narrow) of burner, namely causes system misoperation; Ultraviolet fire inspection, detection range is wide, uses stable, but be afraid of high temperature, service life is short, price is high.So generally, burner selects the many of ionization fire inspection.In actual use, after fuel burner nozzle uses 2 years continuously, easily occur that ionization fire prison distorted signals or monitoring are less than flame, in this case, have two kinds of solutions: one is the fuel burner nozzle more renewed, two is that ionization fire prison is replaced by ultraviolet fire prison.In the first scheme, an import burner needs about 20000 yuan, and delivery cycle needs about 100 days, and impact is produced; First scheme, a set of ultraviolet flame detection system only needs more than 2000 yuan, and market stock in hand, prioritizing selection first scheme.
Utility model content
The technical problem solved: the utility model is just for gas-fired heater burner longtime running, flame deforms and ionization type flame monitoring designs less than flame situation and provides a kind of crossover sub ionizing fire inspection and the inspection of ultraviolet fire and exchange, and this crossover sub is producing the use of forging burning Gas Forging Heating Furnace just.This crossover sub proposes a kind of ionization type fire detecting/monitoring and converts the inspection of ultraviolet fire to less than flame, do not need to change burner and continue heating means, gas-fired heater burner flame monitoring system is as Fig. 2, crossover sub, M14x1.25 fine thread interface is connected on ionization monitoring electrode interface (2) place of Fig. 2 burner (1)
12mm gas thread (3) pop one's head in ultraviolet (5) connect, monitor signal enters burner controller by crossover sub (4) conversion through holding wire (6), and then merge with gas-fired heater master control, reach the effect that heating furnace continues to use.This system ensure that gas-fired heater continues the normal demand used, under the prerequisite need not changing burner, ensure that the reliability that gas-fired heater forges, meet the performance requirement of heating furnace, achieve the exchange of ionization type fire prison and ultraviolet fire prison, decrease maintenance frequency and the maintenance cost of heating furnace, shorten the process-cycle, boost productivity.
The utility model adopts following technological means:
On gas-fired heater, the length of design crossover sub (4) is 119mm, chooses
25mm45# steel is processed into external diameter
21mm, internal diameter
9mm and
the ultraviolet peep hole of 15mm, at joint internal diameter
one end of 9mm is processed into
12mm gas thread, at joint internal diameter
the other end of 15mm is processed into M14x1.25 fine thread.
The structure of system is: crossover sub (4) is installed on burner (1) ionization monitoring electrode interface (2) place; Ultraviolet probe (5) is installed on crossover sub (4)
12mm gas thread (3) place, adopts holding wire (6) to be installed to by special for ultraviolet type flame monitoring R4343E burner controller on ultraviolet probe (5), connects with gas furnace control system, debugging combustion system.
The utility model has the advantage of:
The long-term work of gas-fired heater fuel burner nozzle is under about 1300 DEG C, thermal-flame radiation, oxidation cause burner hydraulic performance decline, flame slightly slight deformation time, the flame (reason detection range is narrow) less than burner just monitored by ionization type fire prison, namely system misoperation is caused, by the exchange of crossover sub, completely eliminate the chance failure of heater control system, ensure that gas-fired heater continues the normal requirement used smoothly.This translation interface, structure is simple, is convenient to make, low price.Solve and produce large problem: one is solve ionization fire prison and ultraviolet fire prison interchangeability problem; Two is solve when burner occurs that monitoring is less than flame, spends less, repairs fast, improve usefulness.This crossover sub achieves the exchange of ionization type fire prison and ultraviolet fire prison, meets gas-fired heater and continues the normal technical requirement used.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model crossover sub structural representation.
Accompanying drawing 2 is gas furnace ultraviolet monitor function schematic diagram.
Accompanying drawing 3 is gas furnace ionization type monitoring schematic diagram.
Detailed description of the invention
Specific implementation method
Below with reference to accompanying drawing 2,3 and example, technical solutions of the utility model are further described:
The first step: disassemble accompanying drawing 3 burner (1) ionization monitoring electrode (7) with spanner;
Second step: accompanying drawing 2 crossover sub (4) is installed on burner (1) ionization monitoring electrode interface (2);
3rd step: accompanying drawing 2 ultraviolet probe (5) is installed to crossover sub (4)
on 12mm gas thread (3);
4th step: IES258 burner controller used for the ionization type flame monitoring of accompanying drawing 3 and corresponding holding wire (8) are removed;
5th step: accompanying drawing 2 ultraviolet type flame monitoring special R4343E burner controller and holding wire (6) thereof are installed on original IES258 burner controller and holding wire position, reach the effect of accompanying drawing 2;
6th step: connect with gas furnace control system, debugging.
The system of above-mentioned improvement has carried out example operation on gas-fired heater, and through using crossover sub, convert ultraviolet type flame monitoring to, gas-fired heater can continue normal use, reaches the object of exchanging with crossover sub.This crossover sub is new version, and structure is simple, is convenient to make, low price.Solve ionization fire prison and ultraviolet fire prison interchangeability problem, reach repairing and spend fast, less, meet the object used.
