Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] This embodiment is a low calorific value gas fuel (biogas) combustion device, which is composed of a control box 1 equipped with a controller, a power mechanism and a burner body. structure see figure 1 , The control box, the power mechanism, and the burner body are connected as one, and the control box equipped with the controller is arranged at the tail of the combustion device to connect with the power mechanism. Its main functions are: realize purge before ignition, purge after flameout, run full-time fire detection, wind interlock, automatic sequential ignition, start-up of combustion-supporting fan, system interlock and other functions.

[0021] For the connection structure of the controller, see figure 2 , the controller is composed of a combustion controller, the first and second PID regulators, and a combustion compound regulator. High pressure dete...

Abstract

The invention discloses a combustion device, and particularly relates to a combustion device for gaseous fuel with low heating values. The combustion device comprises a control box, a power mechanism and a combustor body which are integrally connected. The control box provided with a controller is arranged at the tail of the combustion device and connected with the power mechanism, a combustion fan of the power mechanism is connected with the combustor body positioned at the front of the combustion device, a motor is connected onto a shell of the combustion fan, an anti-backfire device of the combustor body is disposed at a gas inlet, a burning torch is arranged in the center of the combustion device and positioned in an ignition rectifier, the ignition rectifier and a cyclone are positioned in a gas distributing pipe, a mixing adjusting ring is arranged on a shell of the combustor body, and a high-temperature combustion stabilizer is disposed at a flame jetting port of the combustor body. By the aid of the combustion device, the gaseous fuel with the low heating value is combusted safely and sufficiently, and the combustion device is simple in structure and fine in economical efficiency.

Description

technical field [0001] The invention relates to a combustion device, in particular to a combustion device for gaseous fuels with low calorific value (blast furnace gas, coke oven gas, biological gas, producer gas, biogas, coal bed methane, etc.). Background technique [0002] Gas fuels with low calorific value are widely used in life and production. Blast furnace gas and coke oven gas are by-products of steelmaking and coking. Biogas and biogas are the transformation and utilization of domestic waste. Biomass energy refers to the energy converted from natural plants, manure, and urban and rural organic waste. Biomass energy is a kind of renewable energy, which is the energy stored in biomass by plants converting solar energy into chemical energy through photosynthesis. Compared with coal, biomass fuel has low C, N, S, and Cl contents, high O content, high volatile content, low calorific value, easy ignition, and combustion to generate CO 2 , SOx, fuel-type NOx low charact...
