Biomass energy continuous steam supply numerical control normal pressure boiler

Abstract

The invention relates to a biomass energy continuous steam supply numerical control normal pressure boiler, which comprises an automatic feeding device and a boiler body assembly connected with the automatic feeding device, wherein the automatic feeding device comprises a feed box bracket, a feed box fixedly arranged on the feed box bracket, a stirrer arranged inside the feed box, a conveying barrel arranged at the bottom of the feed box and communicated with the feed box through a feeding hole, and a pusher main shaft arranged inside the conveying barrel and provided with a motor; and the boiler body assembly comprises a main boiler body, a first auxiliary boiler body communicated with the main boiler body through a first firework pipe, a second auxiliary boiler body communicated with the first auxiliary boiler body through a second firework pipe, an exhaust port communicated with the second auxiliary boiler body and a water jacket arranged outside the first auxiliary boiler body. The boiler enlarges the absorption area of the boiler body on heat in firework, improves the thermal conversion efficiency by 30 to 40 percent compared with a traditional boiler at market, realizes low-temperature discharge of smoke waste heat at the temperature of below 200 DEG C at the exhaust port, improves the utilization rate of heat, and does not need a fireman to look after for long time so as to relieve the manpower intensity.

Description

technical field [0001] The invention relates to the field of biomass energy, in particular to a biomass energy continuous steam supply numerical control atmospheric pressure boiler which uses biomass as fuel and can realize automatic feeding and automatic water addition to the furnace body according to a water level sensor switch. Background technique [0002] At present, most of the existing atmospheric pressure steam supply boilers in the market are composed of a furnace body, a water jacket, a furnace and a chimney. The water jacket and the furnace body can use the heat generated by coal combustion to generate steam. The flame of the furnace rises directly and is discharged from the chimney. The temperature of the chimney is above 400°C, and the heat loss is relatively large. The biggest disadvantage of the pot is that it cannot supply steam continuously, and it is only limited to the volume of the water tank consumed by itself. Evaporation, during the gas production proce...

[0002] At present, most of the existing atmospheric pressure steam supply boilers in the market are composed of a furnace body, a water jacket, a furnace and a chimney. The water jacket and the furnace body can use the heat generated by coal combustion to generate steam. The flame of the furnace rises directly and is discharged from the chimney. The temperature of the chimney is above 400°C, and the heat loss is relatively large. The biggest disadvantage of the pot is that it cannot supply steam continuously, and it is only limited to the volume of the water tank consumed by itself. Evaporation, during the gas production process It is not possible to replenish water continuously, let alone supply steam continuously for a long time

Refueling still requires manual work, which is time-consuming, labor-intensive and inefficient
