Multi-stage, atmospheric gas burner for boiler, esp. in power range from 70 kW

摘要

The gas burner consists of at least two separate burner modules (4,5), whose gas delivery lines (7,8) are fitted with automatic fire regulated ignition gas and main gas valves (9,11), lead from a common gas feed (3), and an ignition system (6). The valves are arranged in the gas delivery lines as a gas combination regulator by allocating modulation coils, and pressure regulators and are connected to a single automatic fire system. The ignition system devices are only mounted on one burner module, whose effective burner areas are arranged in mutually unrestricted ignition proximity. The module with the ignition system devices has a pressure switch that interacts with the drive for the main gas valve in the other module.
