Gas-fired warmer with dual gas sources

Abstract

The invention discloses a dual gas resource gas heater, which can use high combustion valve gas as gas resource and use low combustion valve gas as gas resource. it comprises a frame (1), a main control valve (2), and a burner (3) mounted on the frame (1). It is characterized in that: the input of main control valve (2) is connected to the gas outlet of dual-pressure stabilize valve (5) whose one gas inlet is connected to the gas resource; the output of main control valve (2) are divided to two ways to connect the switch (4); the switch (4) has four outputs; the ignite electrode (603) of non-oxygen protective igniter (6) is connected to the igniter (8); the dual gas resource jet (7) is mounted on one side of burner (3); the non- oxygen protective igniter (6) is fixed on the burner (3) whose ignite jets (604, 605), thermo couple (602), and electric fire electrode (603) are all inserted into the burner (3).

Description

technical field [0001] The invention relates to a gas heater, in particular to a gas heater which can be connected to two kinds of gas for heating in the same heater, in particular to a gas heater with dual gas sources. Background technique [0002] At present, with the continuous improvement of transportation technology and the increasing shortage of oil resources, natural gas, biogas and other low calorific value gases have gradually entered people's daily life, and the single energy source in cities is being gradually broken by the multi-energy supply system. At the same time, it has become possible to connect the gas supply pipelines of coal gas, natural gas, liquefied petroleum gas, biogas and other energy sources. People can choose the appropriate gas to use according to market price changes and gas supply conditions. Taking gas heaters as an example, in the past they were all single liquefied petroleum gas or natural gas dedicated structures. Due to the different calo...

Problems solved by technology

Taking gas heaters as an example, in the past they were all single liquefied petroleum gas or natural gas dedicated structures. Due to the different calorific values ​​of various gases, the output pressure and gas volume will inevitably be different. Therefore, users must first determine the The gas source used, and then select the appropriate product according to the gas source. In this way, on the one hand, when the user needs to change the gas type, he must re-purchase a new gas appliance, or carry out technical transformation, resulting in increased user investment and social resources. On the other hand, it also creates problems for product distributors. It is impossible to predict the quantity of a certain type of gas appliances, and there will often be a backlog of one type and the phenomenon of another type being out of stock.

At the same time, for a family, it is generally most likely to have two kinds of gas sources. If a gas appliance that can satisfy the use of two kinds of gas sources can be designed, it can basically meet the needs of most people. The needs of most users, and as far as the applicant knows, all types of gas heaters currently available on the market are heaters of a single gas type, which cannot be used universally. Users must first determine the gas source used before purchasing Corresponding types of gas heaters, there is no gas heater that can be used for two kinds of gas for users to choose
