Abstract

The invention relates to a biofuel boiler smoke discharge afterheat utilization system. The system comprises a water feeding pump; an outlet of the water feeding pump is connected with an input pipe; and the input pipe is connected with an output pipe through a third gate valve. The system further comprises a boiler; a joint for inputting water is arranged at the top of the boiler; the joint is communicated with the output pipe through an adapter; output pipes positioned at two ends of the third gate valve are respectively connected with a first pipeline and a second pipeline; the first pipeline and the second pipeline are connected to two ends of an energy economizer; the first pipeline is synchronously communicated with the input pipe; one ends, near the boiler, of the output pipes are connected with booster pipes; and the booster pipes are connected with a booster pump. As the booster pump is arranged between the energy economizer and the boiler, the water inlet pressure of the boiler is effectively increased, the water inlet speed is accelerated, and the long-time afterheat dissipation is prevented.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler waste heat recovery and utilization system. Background technique [0002] The gas-fired heat carrier boiler in the prior art has a low recycling rate, which often causes energy waste; the pipeline between the boiler and the economizer is long, the water pressure input into the boiler is small, and the water inlet efficiency is low. Contents of the invention [0003] In view of the above-mentioned deficiencies existing in the prior art, the applicant conducts research and improvement, and provides a biofuel type boiler exhaust heat utilization system. The present invention adopts the following scheme: [0004] A biofuel type boiler exhaust waste heat utilization system, including a feed water pump, the outlet of the feed water pump is connected to an input pipe, and the input pipe is connected to an output pipe through a third gate valve; it also includes a boiler, and ...
