Problems solved by technology
[0004] The first object of the present invention is to provide a preheating system with multiple boilers connected in parallel. The preheating system solves the problem of differences in the flue gas temperature of each preheater, and can realize automatic control of the flue gas temperature of each preheater. Make the flue gas temperature of each preheater basically consistent, ensure the heat exchange effect of each preheater, and prolong the service life of each preheater; the second purpose of the present invention is to provide a control system for a preheating system with multiple boilers connected in parallel method

Embodiment
[0028] A multi-boiler parallel preheating system and control method, figure 1 As shown, including a plurality of boilers 1, in the present embodiment, the boiler 1 is 3, each boiler 1 inlet water port is connected in parallel through the boiler water pipe 9, and each boiler 1 has passed through the boiler. The water pipe 10 is in parallel with the boiler outlet butter tube 11. The water jet pelvis 5 through the boiler water pipe 9, heat through the boiler 1, heat through the boiler 1, and the water after the boiler 1 is heated, and the boiler water pipe 10 is collected into the boiler out of the water pipe 11, through the boiler out The water drum is discharged.
[0029] Each of the smoke ports of each boiler 1 is connected to a preheater 2, and the water port of each preheater 2 passes through the preheater inlet adjusting valve 3 and the feed mother tube 5, each preheater 2 The tobacco port is provided with a temperature sensor 4, the preheater feedback adjustment valve 3 and th...

The invention relates to the technical field of boiler heat supply, in particular to a preheating system with multiple boilers connected in parallel, which comprises a plurality of boilers, a smoke outlet of each boiler is connected with a preheater, a water inlet of each preheater is communicated with a water inlet main pipe through a preheater water inlet regulating valve, and a water outlet of each preheater is communicated with a water outlet main pipe through a water outlet regulating valve. A smoke outlet of each preheater is provided with a temperature sensor, and the preheater water inlet adjusting valves and the temperature sensors are connected with a control device. According to the technical scheme, the temperature sensor is used for monitoring the smoke outlet temperature of the preheater, the control device controls the preheater water inlet adjusting valve according to the smoke outlet temperature of the preheater, and therefore the water inlet amount of the preheater is adjusted, automatic control over the smoke outlet temperature of all the preheaters is achieved, and the smoke outlet temperature of all the preheaters is basically consistent; and the heat exchange effect of each preheater is ensured, and the service life of each preheater is prolonged.
Description
Technical field [0001] The present invention relates to the field of boiler heating technologies, in particular, to a preheating system in parallel with a plurality of boilers and a control method thereof. Background technique [0002] The boiler is an energy conversion device, and the energy input to the boiler has chemical energy, electric energy, and boiler output having a thermal energy, high temperature water or organic heat carrier, the hot water or steam produced in the boiler can be directly produced. And the people's life provides the required heat, or converted to mechanical energy through the steam power unit, or then converts mechanical energy through the generator to electrical energy, the boiler is mainly divided into hot water boilers and steam boilers, hot water boilers are used to provide hot water, mainly For life, steam boilers are used to provide steam, mostly in thermal power stations, ships, locomotives and industrial and mining companies. [0003] Smoking t...
