classification
Gas incinerator is divided into natural gas incinerator and metropolitan gas incinerator.
According to the incineration control method of the incinerator, it can be divided into single-stage fire incinerator, double stage fire incinerator and proportion adjustment incinerator.
According to the fuel atomization method, they are: machine atomization incinerator and medium atomization incinerator;
According to the layout, they are: integrated incinerator and split incinerator. This split type incinerator is mainly used in industrial manufacturing. Its main characteristics are: the incineration system, air supply system, control system, etc. are all explained and arranged. This kind of machine is mainly suitable for large buildings or high temperature and other external environment.
In contrast, due to the mass production of the incinerator for trade and the low demand for professionalism in the environmental trend supply chain, the environmental trend selling cost of the product is relatively cheap, while due to the relatively high demand for professionalism of the split incinerator, as well as the numerous demand for professional placement troops, the environmental trend selling cost is relatively higher than many years ago.
truth
When the combustible gas (city gas, natural gas and liquefied kerosene gas) is controlled by the microcomputer control system into the incinerator head according to the French mode, the primary air and combustible gas are mixed, and the incineration is carried out, and the secondary air is used to support the combustion, so as to complete the sufficient incineration. The burning state is controlled by the inspection of the active flame tracking system. When the burning is found to be obstructed (lack of oxygen in the combustion chamber, under pressure of combustible gas, interrupting the flow of combustible gas, and insufficient space), the control system will issue instructions, the solenoid valve of the gas supply system will be closed quickly, the power supply will be cut off, and the incinerator will be shut down after the active purging to guide the obstruction.
control
Because the fuel of gas incinerator is divided into natural gas, liquefied kerosene gas, city gas and other combustible gases. These fuels are inflammable and explosive dangerous gases, and they all respond to safety in the process of application and storage. Otherwise, there will be huge safety chaos.
(I) power on operation:
1. Before commissioning, the newly installed furnace body shall be inspected to see whether the fuel gas meets the requirements of the incinerator; the inspection instruments on the air supply pipeline shall be inspected to see whether they are normal, whether the opening and closing of pipeline valves are normal, and whether they are convenient for future application and inspection.
2. For newly installed pipelines, it is necessary to really check the reliability and tightness of all pipelines.
3. Users of the application independent gasification station shall ensure that the space supply and gas supply parameters meet the requirements of safe incineration.
4. Operators should read the building application analysis book, and be familiar with the common sense and skills of safe control.
5. Check whether the gas valve is opened before starting each time, otherwise the incinerator will not work.
6. Start the power control button on the control cabinet, at this time, the digital display shows the current furnace temperature, which is the ambient temperature of the newly installed furnace body.
7. Start the fan control button, and the fan placed on the furnace body will do the work. At this time, if the fan destroys the control cabinet, the active guard will not come in for the next operation.
8. When there is no special sign of combustion supporting fan, start the burning control button. At this time, the burning French controller is the first thing. It experiences the inevitable French way of burning, air supply, flame inspection, and other French ways to finally complete the safe burning.
9. When the incineration controller receives the lamp number that is not conducive to incineration (for example, the incineration fails, the air pressure is not consolidated, the circuit is in doubt) and other questions, the incineration controller will shut off the gas and send out the alarm lamp number.
10. If the incineration controller gives an alarm, it must be manually reset by the operator after handling the obstruction before continuous operation.
11. For the operation of all buildings, the operators shall refer to the safe operation procedures of the furnace body and the manufacturing process requirements for the operation.
12. When the control temperature is adjusted according to the manufacturing process requirements, the operator shall refer to the intelligent numerical control table analysis book for adjustment.
(II) shutdown operation:
(1) there are two environments for shutdown: the first is that when the temperature in the furnace reaches the set value, the controller will automatically shut down, and the operator does not need any manipulation at this time. Compared with that when the temperature in the furnace is lower than the set value, the controller will automatically start up.
(2) the second is: when the salary is shut down and the shift is assigned to shut down, the operator shall operate the shut-down according to the opposite order (A. first close the burning control button, B. then close the fan button, C. finally close the power button).
(3) the operator shall close the valve of the gas pipeline in the environment with long shutdown time to avoid gas leakage.
Domestic development
At present, the domestic gas incinerators are still in the stage of research and demand. It's important because of the question of Ping An quality. Because gas is different from other fuel incinerators. Once gas leaks, it will be totally different from the dangerous level of coal-fired oil incinerators. However, the domestic development rate is fast and matching. In the 11th five year plan, a group of medium and small enterprises with strong technical force have sprung up. Their incinerators Therefore, it is necessary to become one of the small batch of domestic incinerator brands that can win the international market. The factory's advocacy plays an important role. However, the main reason is that excellent gas and atmosphere premixed, semi premixed and turbulent mixing reflux incineration technologies are adopted in the plan, which improves the incineration compliance, increases the incineration intensity and flame solidity, and happens to be international (such as riyalu, Italy, etc )Although the result of gas incinerator is the same, but because of the low cost of China's original cost, it is in a low price state in the world. Whether there is doubt about such a mode of selling, but it is also an international environmental trend of high technology and low price opening. The combustion of low calorific value gas is strengthened by adopting the back flow discrimination stage ignition technology. The optimized burner layout and the different flame patterns of the firepot brick can make the flame pattern cylindrical,
